So I just dropped a 3800 N/A into a 1986 Fiero and am having trouble getting it started. (If this post needs to go elsewhere let me know)
Car:
1986 Fiero
4 speed manual
Engine:
3800 N/A out of of 1996 Buick regal
What I did:
-Did the wiring myself, so I believe that is the issue.
----Spliced all the wires, soldered them, added electrical heat wrap, and taped it all up
----I followed this for pins coming from the CPU
----I followed these for the C203 and C500 connectors on the car
-Had the 1996 3800 computer reprogrammed
-I have installed this fuel pump over the stock Fiero pump
The situation:
-Have power to the car(lights, radio, starter, etc)
-When I turn the key to start, the engine cranks but won't start(not even firing once, no fuel leaks).
-Car will fire with starter fluid, but only a few times
-When I detach the fuel lines(from the injectors) and put the key in accessory mode, fuel comes pouring out of the lines(but not spraying)
----I can hear the fuel pump relay tick multiple times(usually twice) when I put the key in accessory mode.
Options(what I need your help on):
Option 1: Fix it myself
-How do I troubleshoot wiring problems?
-Local auto store doesn't lend out fuel pressure testers, how can I test fuel pressure?
Advantages:Cheapest, forces me to learn about the electronics
Disadvantages: Time(its a project car, but has been sitting for a year+ now), I might not be able to ever get it running, there are other things to do on the car that will also take my time(that I know I can do).
Option 2: Take it to a mechanic
-Where/how would I find the right mechanic, and would they even entertain fixing it?
-How much money should I be looking at?
Advantages:Will get done right, and quickest
Disadvantages: $$, cost to tow, cost to do it
Option 3: Send out the wiring harness
-Send to get it fixed
-Think it is going to cost more or less than having the whole harness redone?
Advantages: Has a way of testing the harness for usability
Disadvantages: Longest time(takes over a month), What if its not the wiring?
