No start help!!
I have a strange problem?
I ordered up all new injectors from FIC and installed them, fun stuff. Took my time, disconnected the battery and everything. No I have a no start problem. Pretty sure it?s not the injectors, I smell fuel and had a fuel pressure gauge on the rail, shows a drop in pressure as it cranks. Put a coil tester online with a spark plug? no spark! Pull the plenum back off to check all my connections, even took them off to make sure no bad connectors, put back together. Still no start. No codes come up, fuses are good, key on, security light is off?. What am I missing? Please help! |

You're positive everything is plugged in?
Check for bent pin on the ignition module that pain in the *** that's on the plenum.

Re: No start help!!
Just in case it's not entirely clear, the ignition module is the device that lives on the bottom side of the plenum.
It's also known as the DIS module. It has connectors in front and the back. It's very easy to bend a connection pin on either of the plugs, especially the one on the back. Suffice to say, it is a serious design flaw, that really should never made it into production. Given all the other stuff going on under the plenum, it's the only thing that will stop the coils from firing. Good luck!! Crabs

Re: No start help!!
Check inj 1 fuse, is it blown?
If yes, you may have pinched an injector wire in between the upper and lower plenum. Start there, a dead inj 1 fuse signifies a grounded hot wire to the injectors, coils, control module.. easy check John |
