I've got a 88 F-150 with a 302 in it for a yard truck that isn't starting.. I've replaced the battery, alternator, coil, plugs, wires, cap, rotor, ignition module, and fuel pump relay and still wont start. I have spark, starter cranking the motor but noting else.
I need help/advice since I'm losing my patience with this truck since it ran Saturday afternoon and haven't been able to get it started since
+1 on the fuel. If you have spark and fuel - you ought to be getting something - farting, backfiring, etc.
Just out of curiousity - what prompted you to change the fuel pump relay? An unusual choice for the first round of troubleshooting.
Make sure you hear the two-second fuel pump charge when you roll the key to On. If not, may want to verify that the inertia switch has not activated before diving into fuel pump replacement or the like.
Not knowing what part of the country you're from - is there any possibility of fuel line icing?
sounds like a fuel pump whine, 4 bottles of Dry-gas in the system since I'm in Maine, the Inertia Switch has not been activated.
The truck ran fine Saturday afternoon. Plowed the drive then parked it for the night. Sunday morning I went to start it up to move it and nothing but click, I took the battery and alternator out so they could be tested which the alternator was bad and the battery just needed quick charge from me trying to start the truck.
The reason why I changed the Fuel Pump Relay is I had someone listening for the whine and didn't hear anything. it is supposed to warm up in the next couple days to 36 degrees since it's been down in the Teens and below.
wife did the spur of the moment/good deal buy on this truck since it has a 7 1/2 foot Fisher plow on it back in the late Spring which we haven't had any problems up until now. I've used this truck weekly during the Summer and have used it Thursday 12/18 and Saturday 12/20 to plow but when I really needed it on 12/21 and 12/22 for the 18 inches of snow it don't want to start
I would check for fuel pressure at the fuel rail. Maybe you have some sort of blockage in the lines somewhere. I have found that when you get an older truck unless you knew all of the previous owners, there could be any form of redneck repairs done to it. This is especially true with plow trucks. Before you keep throwing parts at it I would do the fuel pressure test. If pressure is good at the rail then I would check the injectors. For the heck of it I would also check for vacuum leaks.

there are two little wires found on these older trucks that ground out the fuel system i had the same exact problem when you hooked the battery back up did you install these? there fairly small id say 16 gauge.. but they come out by the radiator where there is wire gromet...try this if its not hooked up..i guarentee itll work..trust me i went through two computers a started an altenator and 3 fuel pump relays..=D
had my truck running... when the outside temp dropped truck wouldnt start and seemed like a dead battery at times. hooked the jumper cables up and still seemed like a dead battery.
the other day, it warmed up to mid 30's and when I got home it was about 27 out and the truck started and ran fine. next day with snow in the forcast, NOTHING! again got home tonight with the outside temp around 25 and it started up.. I came in the house for a few minutes while it warmed up only to back out and find it had stalled out. it cranked hard but started and soon as I took my foot totally off the gas, it stalled... no it dont want to start and cranks real hard even being jumped... wtf
this weekend I'm putting in a new Fuel filter and changing all 3 Battery Cables.. btw snow is in the forcast for this weekend also
fuel pumps are running when I turn the key on and with the hood open I hear a click from a relay also...

Reason: getting frustrated
well i had a starting problem once and i heard the fuel pump turn on and everything and the first time it did it was it stalled out in a mud pit and would turn over but never start up so i popped the hood and was getin a lot of fuel pressure which i ruled out it wasnt blockage so then i thought water was some where where it wasnt supposed to be to i had a buddy of mine pull it home and i went to work and it turned out it was a loose wire that gives the fuel injector power and has 2 relays to it try that out
My vote is for the ignition module screwed to the distributor
or a loose wire/bad ground
It could also be the sensor inside the distributor
Any parts store can test the module and if that is fine then it could be that sensor and it is easier and cheaper to replace the whole dist than to try to relplace the sensor
the hard starting is due to the timing being off!! Had the same issue when you moved the dist you altered the timing... may start fine when cold, then not when warm... or vice versa. you need to get the timing dead on, then remember to remove the spout connector to adjust the timing. then after it's all set to the specs on your emmision sticker then install the spout connector, you should be G T G
when you reset the distributor, did you have the spout connector out? did you set the timing with a light? i'm not saying it will fix your start problem, but the timing does need to be right, i'd go 12*
