ok so i was trying to clean up the car for the spring and got the the carb i sprayed some gum cutter in the carb closed then open butterfly re attached everything and now the car wont turnover. any suggestions?

 

carburetor ? what year/model car is this, with what engine ? we're not mind readers. Volvo hasn't used carbs in the US market since way way long ago, like mid 1970s, but you could well be overseas, although you gave us no clues on that, either...

and, 'gum cutter' ? what exactly did you spray?

 

its an 88 so it may not be a carb but it has a buttfly valve i guess its a fuel injector. 88 240 dl wagon. sorry about the lack of information. Its name is Gumcutter its made for carbs and choke

 

is that a 1988 240? 740? B230F (US market EFI engine) or B230FT (same w/ turbo) ?

the proper term for the part on a fuel injected car is 'throttle body'. the fuel injectors are a different part, 4 separate injectors that are plugged into the intake manifolds right near the head.

did you remove the throttle body from the car before spraying this stuff into it? did you reconnect all the vacuum hoses properly, along with the idle switch?

now, when you say the car won't turn over, do you mean its not even cranking when you hit the starter switch? or its cranking but not firing?

 

sorry i posted that further in the post its a 240 dl wagon.

no i did not. im not i left it on. just opened up the valve.

for lack of a better method of expression its going chug chug chug chug while i hold hte key in start but will not start the engine on its own

 

ok so the starter is turning over, but the engine isn't catching.

this could be lack of fuel, or lack of spark. after trying to start it, pull a couple spark plugs, inspect the electrodes. are they damp with fuel? then its likely a lack of spark. if they are dry, odds are no fuel is getting into the cylinders.

I will often use a timing light to see if there are spark pulses while cranking over. then based on that information I'd proceed with additional tests depending.

 

Pierce you are a life save for helping.

i thought it might be the plugs so i checked and they are dry so my original understanding of it being flooded was incorrect. i took the air intake off so its just the throttle body and it still wont start but i do not smell any gas. i am presuming this means i lost it some where along the gas line?

thanks for all the help so far i appreciate it.

 

the LH system uses a mass air meter thats between the airbox and the throttle body to meter how much air the engine is sucking in, so it knows how much fuel to inject.

neither the fuel injection OR the spark will fire if there's no timing pulses coming from the hall sensor in the distributor.

the fuel pump relay, which on a 240 is behind the glove box, is a frequent source of problems. you can bypass this relay with a jumper on the fuse panel, I believe its fuse 1-or-2-or-3 that you jumper over to fuse 11(? whichever is the rear tank fuel pump fuse), if you do this, both fuel pumps should come on immediately and stay on til you remove the jumper. you could then crank the car over and see if it starts, and if it does, then the problem /probably/ is that fuel pump relay. remove the jumper as soon as you've stopped the engine.

 

alright sounds awesome. never jumped a fuse box how do i got about that?

 

Does the engine sound any different when it turns over?

If yes, remove the oil filler cap on top of the valve cover and note the position of the things you can see inside. Or, have an assistant watch when the engine is turned over. Things should change as the engine is turned over. If this does not happen, most likely you have a broken timing belt.

Good Luck

 

i cant get it to turn over.

 

(digs up the 87/88 240 wiring diagram) ... oh, its fuse 4, not 11, hah, probably was thinking of my 740... and its fuses 6-7-8-9-10 that are always hot, not 1-2-3 (1-2-3 are only on when the ignition is on)

get a jumper wire with an alligator clip on both sides. clip one end to fuse 6 (or 7 or 8 or 9 or 10, they are all wired the same) and clip the other end to fuse 4. you can use either side of the fuse contacts for this.... as soon as you touch that jumper wire to fuse 4 you should hear the soft hum of the fuel pump under the back seat running. now with that jumper still in place, try and start the car. if it starts, but doesn't run without that jumper, then your fuel pump relay, which as I said is behind the glovebox, is likely dead.

remove that jumper as soon as you're done with this test...

 

Wait! Now you turn the key and nothing happens? As in the starter does nothing?

 

no i turn the key and it wants to start but won't.

Pierce i checked the fuel pump i can hear it going when i go to start and just to be sure i went and checked to see if the relay was clicking on, it was.

my guess is that i am not getting the spark. im gona check that via screwdriver as soon as i can get some one to turn the key for me while i hold the wire.

 

hey thanks for all the help guys i got it fixed this am.

 

well, what was it?

 

I unplugged the MAF and started it it started rough, so then i checked all the connections for the MAf and plugged it back in and the idle cleaned its self back up.

once again yall thanks for all the help, tryin to keep this old girl running for a while longer.
