Frustated!
Hello ladies and Gents,
A while back, I posted a thread that fuel was found in my oil pan as I was changing my rear main seal. I also discovered my fuel tank had a leak. I replaced fuel tank, fuel pump, rebuilt the carb and now the truck will not start. I also replaced voltage regulator, ignition module, ignition coil, battery. The truck was not starting before I discovered the fuel in oil pan. Motor is turning but will not fire up. Any advise? Ideas of what it can be? Thanks

Yes, check for fuel & spark, go from there depending on what you find.
You don't give any indication as to your engine size so I will assume a V8...
Remove the air cleaner assembly and look in the top of the carb as you fully open the throttle with your hand, you should see two strong streams of gasoline being injected into the bore.
Check for spark... remove a plug wire from a plug, insert a screwdriver, hold it near a ground as somebody in the cab tries to start it. You should see a strong, blue spark.

Yes guys my truck is a V8 351m. I will check for spark when I get home. Like I mentioned before, my truck was running good up until 2 months ago when it died while at idle. I could never start it up ever since. I thought that the fuel in the oil pan wiuld be the culprit but with a rebuilt carb, new fuel pump and tank Im not sure what it could be now. I would hate to call a mechanic and getting an outrageous bill for something minor.

Gas in the pan is an indication of a problem, but that won't keep an engine from starting.
In my experience, gas in the crankcase has happened when the diaphragm in the fuel pump leaked and the entire crankcase filled up with gasoline.
In any event, check for fuel (at the carb, don't be satisfied because there is fuel in the tank) and check for spark.

Describe exactly what it did when it quit. Did it spitter and sputter first? Did it start shaking first? Did it just shut off like it does when you turn the key? Your problem may not be the things you've tried. It could be that it jumped time, busted a gear on the distributor, the timing chain, etc. There are plenty of things that could cause a truck to shut off and not start again.

Rico,
The truck died while running the first time. A mechanic removed a loose wire from an old alarm that was wired to the starter solenoid. After that, the truck started back up and ran with no problems. One morning I tried to start it and no go. I decided to change the rear main seal and discovered the fuel on the oil pan and pin hole leak on the gas tank. From there its all been trouble.

I'd start with a compression check. If the gas was in the oil for very long and you were driving, it could have thinned down the oil and caused some major ring wear. This could also cause bearing failure. If the compression checks out ok, then procede to check for propper timing, and that it is getting fuel and spark. I don't think I need to ask, but, you did change the oil right?

Yeah oil was changed and I believe that fuel was getting to the oil pan from the amount of times tried to start the truck with no success. I drained the battery 3 times trying to start it while checking different things. My dad seemed to think that the carbureator was allowing fuel to sip by into the manifold or possibly a bad fuel pump. The carb was rebuilt by an old school mechanic and the fuel pump was replaced.

If you had fuel in your oil and you've replaced the fuel pump, I'd say you don't have a fuel delivery problem.
Yes, plugs that have been flooded with fuel can be problamtic but the extent varies by manufacturer. I am thinking that you have a no spark issue, could be plugs but considering what you have already changed and assuming you have voltage to the ignition coil my money would be on the pick up coil inside the distributor. Easy enough to check and replace but the first step is checking for spark and going from there.

Frank,
I checked for spark last night and if I did it right I did not get spark. I disconnected a plug wire from the motor. I grabbed a new spark plug, stuck in in the boot of the wire. I held the wire with the plug close to my ac compreesor bracket while my wife attempted to start the engine. I did not get a spark. The ignition coil is new by the way.

the plug needs to be grounded so it can arc the spark.
the bolt part of plug needs to be pressed against the metal of the engine some where.
if not it will not ARC the spark to ground.
