Stone Cold

Trying to get idea's. I have '92 F-150 5.8 V8. Tried starting, it's trying to

start but it will not turn on. I pulled one of the spark plug's and watched it

spark as I turn the key and it did. I turned the gas pump on 3 times and push

on the fuel rail port and gas shot up to the hood. So I figure my pumps work

it's a duel tank by the way. Turn the key and watch the engine fan turn tryin

to start. That time took it to a mechanic. He said engine gone has no

compression. The next morning the engine started right up. No knocking, no

pinging. After it was warm, check engine light came on it started hesitating,

I put it in drive, it acted not much power. I left it alone after that. That

night i tried starting it 3 times, it wouldn't start. The next morning tried

starting it, and it started right up first try. I let it warm up. No hesitation

no check engine light. I drove it to the gas stataion. Ran just fine. I press

the gas to 3 mark on the Rpms. Tranny shifted fine with it. No hest. no

stalling no pinging no nothing. What I don't get is How did it run if I had no

compression? Any ideas, what's wrong. Sorry this is long. Trying to describe

as best as I could

my be the comp. is just so low that when its cold it will just run ok. but when the engine warms up it will expand the metal to that the comp. is just terriable. Do you know what the compression is?

I have a headache after trying to read that post.... Need to know what he found on the compression test. All the cyls should be within 15% of each other.
