Welcome! My name is XXXXX XXXXX I will do my best to assist you with this problem.Ask me about added features such as phone contact anytime if you wish !
do you have a test light ?
its flooding so bad the cylinders will almost be filled with gas ?
Yes is full.and I do have a test light.
ok disconnect all 4 fuel injectors
you will notice all 4 injectors one wire on each is GRAY on each injector
connect your test light clip to BATTERY POWER when cranking it over does the NON grey wire blink your test light or is your test light lite up solid the whole time and NO blinking ?
we checked them and they are working.
it is lighting up.
solid ? correct ? test light connected to positive battery power on all 4 injector wires the NON grey wires when you turn the key on light it up solid ? or solid only when cranking ?
Ricky im sorry for all the questions but I need to be sure to give you the correct answer
solid when cranking.
ok Ricky if when the key is OFF the test light is NOT lit up the wiring to the injectors should be ok
seeing that light solid is showing the computer is NOT pulsing in the fuel and flooding the engine
this can be caused from either a bad computer or a bad ignition module a bad TPS or a bad ECT sensor
if you unplug the coolant temp sensor and the TPS connector will the light still be lit up solid ?
why am i getting any codes.i have a obd11 and it never picked up a code.it said dtc on powertrain has no code.when the engine stalled it made a faint clicking noise.and was smoking behind the engine.can the computer be tested?
the only way it can be tested is in the truck with a scan tool connected to the truck to see what the data list is doing and reading
can you try unplugging the ECT and the TPS and see if the light is still solid ?
if so when the key is on and the light is solid then the odds are the computer is bad with an outside chance of a bad ignition module
i had the ecm tested it's good. i hope it's not in the head.i will keep trying and will let you know.thanks
Ricky the cylinder head should not cause the test light to light up solid with the key on it should be off then when cranking it should blink the test light not on solid
