89 L98 tries to start but won't
I have been reading a ton of old posts trying to figure this out. I have tested with postive results:
injector restistance
coil
spark
ignition module
coil pick up
Engine turns, no codes tries to fire once in a while if you hold the key. Security light is not on (previous owner also said he had the vats program disabled when he had a custom chip burned).
Plugs, wires, cap, rotor, throttle body, tps is new. Fuel pump comes on. If you crank it for awhile you can smell gas.
I want to get a noid light but not sure whch one to test injector pulse. I'm stumped because it will try and start.

Here is a little more info on the car I bought it last july.
