Only three possiblities. no gas, no spark, or the timing of the 2. So first follow the full lines and disconnect and turn on the ignition. That will start the full pump. you should see gas flow. Next remove a plug wire and dont hold it but place it near a plug or anything metal on the engine. You should see a spark when cranking the car. Finally its the timming of the two. remove spark plug from number 1 cylinder, with a wrench turn the crank shaft around untill the cylinder comes to top dead center. Look through the spark plug hole you should see the piston top. Now take off the distrbuter cap and look to see which terminal the rotor is touching. follow the wire and make sure it is the same wire that goes to the number 1 cylinder. Of course if the distributor rotor isnt rotating then of course your timing belt is broke. Good Luck.

Ok I am wondering if my motor in my 91 gmc 5.7 l b8 is a vortec or a 350 it has throttle body carb and not sure thought if I could interchange it with an older 350 ..


Here, is what I think you are asking. The TBI intake from a 91 will fit the same size engine from 88 to 95. The Vortec didn't come out till 96 I believe. So if your 91 is the original engine then it is not a Vortec motor. If you want to swap your 5.7 with another 5.7 (5.7 = 350) Then the 88-95 should work, Just double check your sensors and locations as the plugs may be different and or in different locations. I know my 88 GMC and my 94 chevy (both K1500's) were a little different. Hope this helps.

I ran out of gas in my 91 maxima and it cranks but it just wont turn over and start is it the fuel pump or an electrical thing


if its a stick/manual,push start it,if its auto,crank it but dont step on the accelerator,sometimes,u can flood the engine when u put fuel in and u crank with your foot on the gas pedal.follow your air filter all the way to the carbuerator,open it and then crank,be careful,u might get a flash bang from all the air flow,good luck

My 1993 Olds 88 wont start cranks but wont kick over. Fuel prob


3.8 are known for ignition trouble but first use the fuel release valve located on top of engine under a screw cap to see if your getting fuel. It takes 4 things to make engine run fuel spark air and compression. But most likely the Ign control module or crank sensor. So try this
1) check the fuel pressure
2) check for spark
3) compression test
