Ignition Problems

[ccorbin81]

Hi,

I have an 88 Supra Turbo and recently it has had ignition problems. It turns all day but will not fuel because the pump isn't recieving power. The B+ terminal is dead, if I jump 12 volts to it the car starts and runs beautifully.

I replaced all fuses in the kick panel and fuse box under the hood including the alternator fuseable link. I have power to the IGN fuse in the driver kick, power to the EFI fuse and EFI Main Relay, I have removed the glove box to gain access to the ECU but I am not very good with wiring schematics and I don't know what circuits or wires to test on the ECU. I did check as many grounds as I could find and they all are clean and secure. I replaced the ignition switch but from what I read it was gaining power on the correct wires off of the switch anyway.

It has been very wet here lately and I fear there may be a short. Is there a dummy's guide to troubleshooting this circuit?

Can someone assist me with what I should do next?

Thanks in advance
