| 1> Start small and cheap: check your wiring. No cracks or burns. Make sure there's ample voltage going to your pump or your relay or whatever you're working on. |
2> Then trace back, if the problem's not here, it's somewhere else! Trace your wiring, trace your lines, be patient!!
3> BUY A MANUAL! Idispensable item!! I bought a Hayne's manual for every vehicle I ever owned.
4> Make sure you know what you have! Unless you bought this truck brand new, other people have worked on it and changed who-knows-what! There might have been a motor swap or additions might have been made or someone who didn't know what they were doing might have botched something. Check everything against the manual to ensure it's done correctly.
After many days of working out in the fricking cold (live in Montreal), my truck finally seems to be running nicely.
I started by checking the cheap stuff as I said in my earlier post, and just replaced faulty stuff as I found it.
My problems seem to stem from an engine swap that was only half doneproperly. I have found wiring shoved wherever, spliced, cracked, shorted and burnt all over. My fuel pump was only running on half voltage(not supposed to be possible) and once I had it pumping properly I found that crack in the TBI fuel meter body. I found that I had an almost brand new EGR on the motor, but the fricking lines weren't even connected!
I did replace the pump relay and did blow my ENG-1 fuse once, I checked around the engine compartment fuse box and found that there were a few loose connections...
These trucks aren't terribly complicated and with a bit of tenacity you should be able to trace and correct most problems right in your driveway (I was under it when we got a foot of snow!).
