Truck won't start after head gasket replacement!!!
Replaced my head gasket and now it won't start. I put everything back together the best I could and came out with some extra bolts...and some of those aren't needed. I have changed my timing numerous times and it won't fire. I took off a spark plug and it sparked. I can smell gas. But it won't start...please help...what should I do?

I have spark (checked with timing light) and I have fuel pressure (took of small tiny metal hose...actually loosened it and it squirted all over)...I am guessing it is a stupid piece of sensor causing it to not start. What do you think?

not many people are up and posting at 4am, dude. give it a bit. although, honestly, i think a lot of folks might see it as a lost cause when you say "i took apart my rig, put it back together as well as i could remember, had bolts left over, but i'm sure they're not important"...

Gas, spark, and timing are your best friends, and it only seems like you've got the first two. x2 what Gremlin said. Are you sure that all four are getting spark? Fuses good? Is the smell of gas too strong? I had a gas leak when I tried to start mine and it wouldn't start.

is the cam and crank set at 0?????? if not then you better check that as we have interference motors and they like to go poof. but lets say yeah you got it timed just right (cam and crank) and you got fuel and spark but like they said is the dis set right and not flipped 180?get the crank puley and put it at 0 then take the dis cap off and check to see if the rotor is right at 10:30-11:00 (where the number one plug wire goes) if not set it there ok lets say that thats all right and timing is dead nuts did you check firing order?

Im willing to bet your cam and dist timing are off. Sounds like you were rushing to get it done and now somethings wrong. Take your time. No one ever has time to do it right the first time but always has time to do it over a second time

I too would vote cam or distributor timing. First off, get the distrib right.
Remove #1 plug (that's passenger front) and stick your finger in it. Now have a friend bump the starter, when it blows your finger out of the hole you are approaching TDC. Grab a rachet and socket and turn the crank by hand until the timing mark lines up to 0. (make sure you are turning it in the correct direction)
That'll be TDC. No put the distrib in so that when fully seated the rotor is just slightly advanced from #1 on the cap.
Button it up and start. If it doesn't start now and you've got fuel and spark, I'd bet cam timing and you'll have to pull the front cover off to verify.
There's really only one way the pulleys can go on, so it it's not timed right it's because you didn't line up the marks when you put the belt on.

Thanks for all the replies guys. I could ALMOST get it started last night. It just wouldn't fire. I am going to replace the spark plugs and see how it goes. They aren't in that great of shape. The timing was right on last night and still no go. Thanks again...I will update later.

I dont think your spark plugs are the problem. If it ran before you took it apart and now it won't......makes sense to me that its something you didnt do right or hook up right

Spark plugs fixed the problem it was too early in the morning to diagnose the problem and I could not run to the parts store...sorry for the inconvenience.

So, you got fuel. You got fire. Your cam/crank timing may still be off. You distributor timing with #1 may be way off. Your ignition wires may be timed clockwise when they should be timed in the opposite direction.
Put timing mark at 0. Remove valve cover. #1 intake and exhaust should have about 0.010" clearance. If not, rotate crank one more revolution to 0. #1 piston better be at the top of its stroke. Can put a straw in the plug hole and rock crank left and right. Straw had best go up and down equally.
At 0 with distributor cap off, mark rotor button location with mark on distributor housing. Put cap back on and put #1 wire on cap closest to mark. Then, in correct rotation of distributor, install all the other wires in firing order.
Wet plugs will keep an engine from firing. That is why changing to fresh plugs will ignite the gas. Cold engines are harder to start.
Do all the above, plus use matches and clean your plugs to dry them out, it should start.
And, next time you have an anxiety attack, drop the attitude when people are trying to help you on THEIR time. We don't give a flying crap if you need to drive 500 miles in several hours and you are having a immature fit.
No charge this time.....
