SHO WILL NOT START

[SHOPLUS2NR]

My 91 SHO PLUS will not start. My fan and ac quit working along with no power getting to the fuel pump so I changed the starter relay and the relay control module. Now I've got the ac working and the fan but still don't have any power going to the fuel pump. Can anyone please help? I don't know whatelse to look for?

Your not getting any power to the fuel pump. How do you know, its not making the that sound when you first turn the power on in your car? Maybe time to change the pump...

I just ran a KOEO test and came up with these faults: 96, 59. 96 fuel pump secondary circuit failure, and 59 is low speed fuel pump circuit failure. There is no pump noise before I try to start the car. Should I just get a new pump or is there something else I should check before changing it?

Ground the fuel pump circuit, so the pump runs continually. The result should help narrow your diagnosis.

I grounded the fuel pump and got nothing. The pump wouldn't even run.

Have you tried the switch in the trunk on the driver side? shrug

Sorry, I forgot to mention that I tested the switch and it worked like a champ. It killed the engine just like it should. I think I'm just gonna go with a new pump and see what happens. Anybody have any info on a good pump?

I replaced my pump with one from advanced auto. It was OEM, but it really helped my 89. A lot of people go with the Walbro 190 LPH. Good luck and after you replace the pump you will love the way it drives again thumb

Before spending money on the pump, take a moment and read this very recent thread about the EXACT SAME PROBLEM you are having.

Pointing out the obvious, but the SEARCH tool is exremely handy.

You are exactly right. I checked the fuse and it was burned all the way. Your the heat.. lol Thanks. Now any ideas on how I should go about fixing it?

Buy a replacement, cut the old one out, splice the new one in by soldering it.
