I have a car show coming up real soon so please give me your feeback asap. I have an 89 TPI Camaro. Ok now heres the problem I was driving home from my buddies' house one day cruising at about 50 in 4th gear when all of a sudden my R's just dropped and the car died. It didn't like do anything weird before dying off, the engine simply stopped. I tried starting it up and got nothing. After having it towed back to my house I checked the spark and it was good. Checked the fuel and there was nothing. I replaced all the components of the fuel pump setup only to find out that there still was no power getting to the pump. After doing that, the engine wouldn't even crank the next day. So I went throw all the wiring I could checking for power and where it stopped. I am not getting power to the ECM or the fuel pump relay. The battery has full power too. After reading the schematic in a Haynes Manuel I found that there is an inline fuse somewhere in between the fuel pump relay and ECM. It says its attached an orange wire too. Any ideas as to where that fuse may be or what else may be causing my car to get no power to all the main points.

 

I would definitely hunt down the main inline fuse. It is the main power for the Fuel Pump, and ECM I believe. On my 86 its in a fuse holder up by the batter on the passanger side. Look around in your front fender wells, and areas for 2 wires that end in a little black box which would be the fuse holder. The proper place for it is to be mounted on the inside of the fender by a screw, but on mine it was just laying down by the battery. Good luck! I hope this helps.

 

I agree, most likely the fuse under the hood.
Also check the connectors on the f/p relay and maf power relay, over time the insulation slides down exposing bare wire, sometimes they short out and blow the fuse, wrap any bare wires with elec. tape.

 

thanks alot guys! I found the fuse right away and the pump is now working. There is one other problem though. My car will not crank. I mean there is not a sound coming from the starter or anything. Any ideas?

 

its called karma for hosing me on that lt1 intake!! i hope ur car blows up personally!!

 

-Check the Fusible Links
-Check to see if SES/CEL light is coming on
-Did you pop the Crank Fuse in the fuse block?

There is a fusible link that goes to the starter, and it then theres a purple wire that comes off the starter and goes to the crank fuse.

I have a wiring schematic for my 86 (probably different but might help)
Fuel Pump Relay Wiring
Tan-Wht :
Fuel Pump to FP Relay->MAF Relay->ECM Fuel Pump on signal
(also tan white goes to FP Switch that turns into Orange wire )

Orange: (battery +)
Inline-Fuse->MAF Relay->ECM memory power input + ECM memory power
(also orange goes to FP Switch that turns into Tan-Wht)

Dark Green-White:
FP Relay -> ECM Fuel Pump Control

Blk-White : GROUND
Orange-> Black Red: ALDL Diagnostic Connector

Crank:
Crank Fuse->PPL wire to starter solenoid + ECM

Pink Black:
Engine Control Fuse-> ECM power input->ESC Module
