if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing
sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

Try a new relay first. This may not be good news if that does not work. If you can find the EEC (computer) and unplug it, then replace the fuse-if it blows you have another cheaper part on the circuit thats bad.
If the fuse does not blow, then the EEC must be shorted.
If you have to replace the EEC you may find a kindly dealer with a cash-for-clunker sitting there to violate. Salvage yards have them, Ebay sells them. I have seen them at swap meets for $20. They are a high price part even rebuilt at Dealers or autoparts stores.
SOURCE: where is the EEC relay
This year calls ita PCM relay. Its in the lower row of the six big relays in the engine fue block.. It is on the right side above the two smaller relays. It would be position 6 if you start at the top and read like a book. .The relay above it is the horn relay. Its the same . Rotate them to check. to see ifthe PCM relay is bad. If the horn works with the PCM relay then the relay is not the issue,.

In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to disarm the airbag system can result in an unexpected Airbag deployment and possible serious personnel injury disconnect the battery 30 minutes prior to start of work.
