Ny 98 626 4cyl. is having problems starting. The Haynes Manual says check (jump pins) on the fuel pump relay. I can not find this in the manual. Under the hood next to the black fuse/relay bos are three grey relays. I am assuming it is one of these. I can not find out what any of these three are in the manual. Please help.....

If I remember correctly it is either the one closest to the driver fender or the middle one, but not sure at this time. What kind of trouble is your car giving you as far as hard to start?

You might be on the right track though as fuel pumps were not uncommon on those years of 626.

yah it is hard to hear. Take the top fuel line off the fuel filter and get someone to crank the engine. Is there fuel coming out of the filter? If not you have something either wrong with the wiring to the pump or the pump itself. Also check the EGI fuse in the fuse box under the hood

Suggested Repair

With the top fuel line removed from the fuel filter, have someone crank the engine and check whether fuel comes out. If none does, suspect the fuel-pump wiring or the pump itself. Also check the under-hood EGI fuse. The fuel-pump relay may be the gray relay nearest the driver-side fender or the middle one, but that location was not confirmed.

Conversation Summary

A 1998 Mazda 626 4-cylinder lost power and will not start. The owner confirmed spark and the coil pack, replaced the fuel filter, and could not hear the fuel pump or identify the fuel-pump relay among three gray relays. The technician said the relay might be nearest the driver fender or in the middle, but was unsure. The recommended checks were to disconnect the top fuel line at the filter and look for fuel while cranking, then inspect the under-hood EGI fuse. If no fuel appears, the pump wiring or pump itself may be at fault. The owner's follow-up about testing the EGI fuse with a meter was not answered.
