Hello everyone,

i just got a 88 Baretta boat, with an AQ131D motor, I got the boat and the guy said it needed the fuel pump replaced and he had one that he bought just has not installed. so i installed and hooked up to the fuel line with a primer pump to help get the fuel up to the clear fuel filter that is roughly 6 inchs from the carb. and it still is not sucking up fuel i even tried cutting the hose and sticking it into a one gallon fuel can with fuel and its like its not even pulling fuel. is there a rod for the fuel pump that is missing? or is it cam drivin? i have tried starting fluid and it acted like it wanted to start once then not again. I dont know what the motor sounds like normaly but to me it sounds like it turns over just fine, not too slow or too fast. so i dont think its a timing issue but idk. I have not checked my plugs yet which i will do tomorrow.

what i would like to know is if there is another motor that can take its place, like a L4 chevy motor or something, that can use the same out drive, so i can decide which way i want to put my money into the motor.

Also what volvo vehicles can i use parts from for this motor i have? im not sure what year the motor is in the boat but im guess its an 89, because at work my computer does not find AQ131 for 88 but it does in 89.

Welcome, nice to see another Baretta owner on the forum.

If it were me, I would pull the fuel line off the carb and turn the engine over to confirm the pump is pumping. If it is not, I would check for blockage at the fuel tank/filter. If its pumping fuel to the carb, I would suspect a dirty carb or stuck float.

Not time to look for a new motor yet.:rolleyes:

Good luck!

It looks like it will be a fun boat once its up and running, Would you happen to know where i can get a wiring diagram for the boat?

How would i go about checking to see if my pump is pumping, you said pull off the hose, so im assuming have my wife turn the boat over and see if i can feel it sucking air in?

I would disconnect the fuel line at the carb and, yes turn over the engine. You will need to contain the fuel that exits the fuel line, so...you need to be safe and creative.

Re: Having prolems starting my AQ131D

I looked at parts breakdown of your A131D and I didnt see a push rod for the fuel pump so it must be directly pushed by the cam lobe. If it doesnt pump fuel after you test it according to captmello's instruction then take the mechanical pump off. You cant try to suck fuel out of a can again by manually pushing on the lever and see if that works.

Is there a shutoff valve between you tank and fuel filter? The parts manual does not have a good description but it sure looks like a shutoff valve.

Re: Having prolems starting my AQ131D

i pulled of the hose, had my son turn the motor over while i stuck my finger over the whole, i did feel some suction coming from the pump. so i used a hand pump to pump the fuel to the end of the fuel line, and then hooked it all back up. I tried to start the motor and same the same thing happens it just turns, but i also noticed that there is not fuel squirting out of the jets. so i had my sun turn the motor and i sprayed some starting fluid in the carb and still nothing..

I was going to to pull the plugs and check the coil and do a compression test, but.... all my damn plug sockets are too small lol. so once i make a trip to the auto store later ill buy one.

as far as the shut off valve i dont think there is one i have not seen one anyways. and im getting fuel out of the line if i use a hand pump. you said you were looking at a parts breakdown, was it an exploded view? were do you find this at so i can also look. and does anyone know where i can get a wiring diagram for my boat?

what spark plugs can use in this motor? i tried to google but none of the answers i got were very helpfull. I can't remember off the top of my head but i think i saw an autolite a23 on some website?

Re: Having prolems starting my AQ131D

lets say i was going to rebuild the motor, how do i find out what year volvo i can find parts for the engine, like like the eternals of the engine, pistons, valves, valve guides, etc..... I keep seeing only people using 88 volvo 240 parts but, the only year i see the 240 is in 1990 and above. I would like to completly rebuild this motor, but i have been thinking of maybe changing to the omc 3.0 if its hard to find parts.

i found a head gasket kit on ebay, i was looking through this website's store and coil's and stuff. seems to be decently priced on everything. i had question about the coils but ill wait to ask for when the time comes. I had ordered a tool from work that i can hook up my plug wires to and test them, so once i get them figured out ill ask.

Also it just seem weird to me that there is no engine mount and all the weight is supported by the connection to strendrive and the transom. is there any way i can make some way to brace it with mounts? im sure its normal for boats, but i work on car mostly and just not seeing some sort of support mount is a little weird.

Re: Having prolems starting my AQ131D

Spark Plugs: Volvo #875820-3 (Bosch W6DC) You can get the WR6DC and unscrew the resistor (R) to make the W6DC.

Download the volvo manual for free and you'll have all the blowups and wiring diagrams you are asking for:
Manuals & technical data - Service & Support : Volvo Penta

So you have gas getting to the pump, did you disconnect from the carb like captmello recommended to see if the fuel is getting to the carb? If it is, and you don't have gas in the carb, you need to rebuild the carb. If it isn't getting to the carb then it sounds like your pump is bad.

I don't know why you keep mentioning rebuilding the motor. You haven't yet diagnosed the problem you have, so what makes you think the motor is even in need of a rebuild? Did you do a compression test? A cylinder leak down test? I don't get it.

The coil and plug wires are really easy to just check visually. Just disconnect them one at a time and hold a small distance from the motor and check for spark. The coil spark should be blue/white and not red/orange.

Also, you need to remove that clear plastic fuel filter, those things are a fire hazard. Install a proper fuel filter/water separator between the tank and pump.

I am wanting to rebuild because it looks like its not in the best of conditions and its probably not been rebuilt since it was sold, i have fuel getting to the pump, and i dont see it squirting out of the jets into the carb, so im sure that need rebuilt. they fuel pump is brand new, but thats not to say it could be bad out of the box. I have a spark plug socket on order from work, becuase all mine are too small so i have not had chance to do a compression test, what should it ready when i do the compression test?

as far as testing the coil and wires, i had a buddy who held the wires last time and shocked the crap out him so i am not taking the chance on repeating that test myself. so i have a tool that looks like a spark plug that i can test them which i should have tomorrow.

i never had a problems with the clear filters before, but i am just using it for right now to see if i can get the motor running and if there is fuel getting to the carb. and i plan on replacing later on.

Re: Having prolems starting my AQ131D

ok, so today i have tried to see if i could see a spark with and without this tool

Amazon.com: KD Tools 2757 Ignition Tester Calibrated for Standard Ignitions: Automotive

and neither me or my wife had seen any spark coming from the coil wire, or the plug wires. so should i replace the coil, plugs, wires, cap and rotor? and maybe the point inside the cap?

i say wires because they are horrible looking, basicly coated it some sort of white corrosion that over the rest of the motor. and look like crap.

Re: Having prolems starting my AQ131D

ok, so tonight i put a volt meter on the coil, and it read nothing, but im getting 12+ volts from the battery. Yes i tested the coil with the ignition switch turned on. i pulled the whole harness and it looks good, the fuses from what i seen were not blown, i was looking at the wiring diagram for the motor and i see a relay i do not know where the relay is at.

is there a way i can hook the coil up to the battery directly just to see if it works?

i tried to see what i could from under the dash and it all looked to be ok but the fuster cluck of wires and small area to move was hard to follow. ill probably drill out the rivits that hold the guage cluster in and check them better in the morning. but before i start rewiring anything i would like to know if there is a way to get some direct power to the coil and test that way.
