Look behind the glove box there will be a brown wire with a black strip it will have a disconnect that looks like a fuse holder.disconnect and set the timing then plug it back after timing is set.

I have a 1987 chevy S10 4x4 xcab pickup . it just died one day i rebiult the TBI and put a new computer in it and new coil in . Have checked all the fuses . and it will not start .do you know what i


Check if you have spark (coil or ignition problem) Next consider what you did when rebuilding the TBI as there may be parts that will only operate in one way or settings that have to be adjusted. Lastly is the new ECM compatible with the system (immobiliser) Use a scanner to reset the ecm program

1994 chevy truck will start then dies


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

1999 chevy k2500. changed spark plugs 4 times in 7 months. Runs good for a week then doesn't start. Changed spider, throttle body sensor. Still has no codes and once again won't start.


The next time it won't start ,pull a sparkplug wire and see if you're getting fire.Then we'll known whether its a ignition or fuel problem and go from there.
