oooo had this happen to my Toyota truck, the timing chain broke. how many miles are on this engine?...sounds drastic, but may not be the end of the world.

I agree. If over 100000 and the belt has never been changed I would do a compression check on each cylinder. You should have 150 to 200 psi on each. If belt slipped or broke you probably took out some valves. Compression check will let you know if the valves are ok or not. Good luck

Get the fuel going. Check the fuses and relay, if they check out, replace the fuel pump. Try some starting fluid to see if you have spark.

I agree with tenspeed. Try some starting fluid. The fuel pumps on 91 and 92 will not prime when key is turned on. Might try turning over and checking fuel pressure at fuel rail.

If you have fuel check cam position sensor. It controls your coils.

Does it sound fast and weak when you turn the key? I'm suspecting a broken timing belt. your distributor is tied to this belt and would not turn if the belt were kaput.

Your car does not have a dist. So please don't look for one.

Huh,? guess I'm still in the stone age. Every car had a distributor 93-96. I shouldn't even try anymore-

what are they using now, a crank angle sensor, a cam angle sensor and a MAF sensor and between this soup of information manage to make it run right...well golly, sakes alive-

dandyoun

It's all good. But yes these cars do not have them. They have three coil packs.

Yeah, I remember replacing those on a chevy cavalier back in the day-

Does it appear to be turning faster than it normally did?

dandyoun

Use a spare plug wire and plug to test for spark. Plug it into one of your coils and hold to valve cover to check for spark.

dandyoun

Sorry but what your describing sure sounds like a timing belt issue and yes these cars are known for them causing major issues. When they break they normally take out valves which causes the engine to turn over real strong and fast. It also causes no spark due to the back bank intake cam not turning the cam sensor.

no it turns normally and timing belt wouldnt cause fuel pump not to come on and like i said it was running and driving fine and started spitting and sputtering then jus wont start timing belt is good and tight not wore out its all good

Try 3SI.org. They should be able to help you with how to test your ICM. Good luck

If timing belt is not turning the cam with the cam position sensor on the end of it the fuel pump will not come on.
