Hey guys it's been a while. I hope Bbengineer, IffyG, and ZSPOT are still active. I have a no start issue where my car cranks but will not start. All I did was replaced the old wires with Delco PN#9746BB and Delco 41-101 plugs. Now she won't crank. I have replaced the ICM, TPS, MAF, CKP, IAC sensors, and fuel filter. The crankshaft sensor is about 4 years old though, but I am getting a reading on the 3x signal. I have fire at the coil packs but none in the combustion chamber. The plugs are just soaked with gas. Fuel pressure reads 50 psi. My injectors read 11.9 volts. My coils read 5k ohms. And I'm at a lost. How can it go from working with minor misfires to not running at all. I have DashCommand and a wifi scanner the numbers are all where they should be. 111 RPMS on 3k, 12.94 volts on the battery, and -0.4 on TPS. I gave cleaned and checked the ground for the icm and all. I cleaned the PCM connectors and the bracket that the ICM mounts to. Anyone ever run into this problem or have any idea of what to do? Should I replace the camshaft sensor too? I'm really tired of guessing. I need help from someone more experienced.

engine is flooded with fuel

too much fuel = no combustion




if you keep trying you may damage the engine it could seized

and then you are really screwed


9746BB and 41-101 Iridium are the correct ones I used those. when I replaced them

I also checked a few sites and it's Compatibility chart


are you sure you connected the wire(s) correctly ?
you did one at a time right?


you also did try the old plugs? could be bad batch of plugs?

Pull the plugs back out and check the ceramic for cracks.

Did you replace the fuel pump? does it prime? don't know but i remember on gpf you had a few questions about installing a new pump might want to check that out to as well... plugs aren't the issue...fuel pressure regulator id check too been there so i would work on the fueling first... if that's ok sounds like the crankshaft sensor should be checked as well along with the camshaft sensor

Thanks for your responses. I checked the wires and I have resistance 3k 0hms. My coils have 5k Ohms. I bought some new Autolite 104s and will give it another try. A friend of mine told me to replace the coolant level sensor too. All other sensors have been changed and still no dice. He said maybe the sensor is bad and telling the car it's really cold and flooding it with gas. FPR is new too. I'm really at a fork in the road. Any other ideas?

If you're changing a coolant sensor, make sure it's the temperature sensor and not the level sensor. I don't think that would be the issue - you could just unplug the sensor and see how it behaves that way.

Thanks frank. That's what I'm changing, the sensor on the intake manifold next to the thermostat.

New FPR and still no start. It does crank and start if I spray gas into the intake. I just made a 450 mile trip with no issues. Until I killed the car and had to start it again.

Just for laughs and giggles, try unplugging the Mass Air Flow sensor
