starting problems

[88BII]

truck starts fine in the morning but after you shut it off when its warm it don't want to crank back up, i have to wait about 45 minutes to crank. i check the timing and its dead on 10 degrees with the spout pulled out. i don't understand is the starter maybe getting hot from the exhaust? lmk

You might start by getting it into a state where you can recreate the issue and start testing at the starter solenoid to figure out where the voltage is or isn't. Keep in mind you will likely need to have someone turn the key or you might have to put together a jumper wire to the solenoid to "fake" the key ignition signal.

If everything looks good going to the starter, then your problem lies there..

this sounds awfully similar to a problem I had with my old 5.0 the module on the distributor gets hot and starts acting up. try rubbing a wet paper towel on it when its hot and see if that fixes it.

vapor lock sounds possible too.

low_five... vapor lock would be a good possibility, except I doubt it.... and only because of his description of his problem being that it won't "crank up" until 45 mins later... his starter could be faulty, or his solenoid.

if it cranks but doesn't start... then yeah, vapor lock sounds like a cause... how to diagnose that.... when it won't start, take the fuel schrader valve cap off and push down on the schrader valve after cycling the key a few times to build fuel pressure... then once fuel comes out try starting it up again... if this fixes the problem, then it is vapor lock.

you can fix this by having an electric fan that shuts off after the engine gets cool enough, not when you shut the engine off. (I hooked mine up to the cigarette lighter power)

get back to us when you figure it out.

yep I didnt read his post right. sounds like he cant even turn it over now.

yea its like i have a dead battery, but its not voltages check are 12.2-12.5 so the battery is good and i know the alternator is good because its 3 weeks old. all the voltages check out fine at the starter and at the solenoid. the only thing i can think of is that the starter is getting hot. let me know what you think.

This sounds identical to a problem I had with one of my old Volkswagens...I realize a Ford and and a 60's aircooled VW are not the same machine, but in any case I would bet a krispy kreme that it's your starter solenoid. I'd replace it ASAP, they're not expensive at all so you won't be out a big chunk of money. Start here.

Do not rule out the ground wire! I have seen this many times where a poor connection at the engine block or a ground wire corroded inside the insulation was the problem.

Next time it acts up use a set of jumper cables and just connect the ground from the battery ground to the engine block and see what happens.

fixed the problem. turned out to be a weak starter.
