Engine Trouble - 2.3L - 1988 Ranger - details inside

[davedsmer]

Ok guys, this morning when I got up the Ranger would not start. It rotates but won't start. I've been slowly trying to narrow down the problem. I am down to looking for the fuel pump fuse.. which I can't find. I also have two new fuel pump relays I am going to put in tomorrow.. bought them since they were cheap to get. I have two because there are two fuel pumps which im sure yall already know. Anyways, where is the fueses located for the fuel pumps because I didn't see fuel pump listed on the fuses under the left side of the dash? I am trying to elimate all the easy stuff first so if there is anything yall can think of please let me know. I already changed out the ignition wires and plugs just to be on the safe side plus they needed it.

Did you check to see if you are actually getting spark? I believe that there is a fuel pump reset switch under the passenger side kick panel check to see if that has been thrown.

well I did check the switch under the dash there and it wasnt tripped. The plugs are getting spark but it seems like they are getting really weak spark. Using one of those OEM testers it would only spark at a setting of 10 which was way below what it should and even then it was a weak yellow arc and no blue.

tfi module. this would cause a weak spark. you can take it to any chain parts store and they can test it.
