Ok I have an issue with my 88 RRC as it won't start. I've spent the last few hours researching and haven't had any luck.
A few weeks ago I went out to leave for work. Turn the key and the 3.5 will just turn over with no fire. After some research I by-passed the inertia switch and hard wired test on the pump which pumped fuel. The truck started fine and ran without issue until last week. Then same thing after running normaly, I go out to go to work and same thing. It will turn over but won't start. So seeing that the inertia switch is by-passed I hard wire the pump to see if it works which it does. I then try to start the truck and joy, it starts right up. Now I have the truck setting behind my house and it won't start again. It will turn over fine and if I hard wire the pump to test it, the truck will start for a second or so and shut down. I thought the Pump was weak and have replaced it with an Airtek and no joy. No, when I first turn the key I can't hear the pump do a precharge. (keep in mind that I do have the rear floor up and have easy access to the pump.
It seems that which ever component tells the pump to start is failing to do so....
