Put timing on, the trunk ran fine, put serpentine belt and it started back firing, put the mass air flow on and the truck jerks and wont start. We have replace all the pullies and the belts and gaskets. We even replaced the spark plugs and the coil packs. We cant seem to figure out what the problem is when we put it all back on. The timing is still correct when we take it all off and check.

Which timing cam? Scan for codes and check fuelpressure first with a gauge autoparts rent it. Check fuses underhood as well.

Its a duel over head cam. The driver side. Fuel pressure is good. Husband did check that. When it started back fireing with the serpentine belt it did have a smell of gas. Fuses are good as well nothing burnt out or missing

Check compression kind of sounds like the belt came off or broke and you aren't telling the whole story. If it did it probably bent valves. Also the pin on some of these can break that holds the cam gear and will spin on cam causing it to look like in time but actually not be.

The reason why we replaced the belt originally is because the water pump cracked an snapped off. We were hoping tge cams weren't bad. Just didn make sence why it ran fine then stopped when everything was assmebled. An the lines do line up still. I honestly think ur right about the valve though. The lady tried starting it with the water pump busted. We prayed it wouldn't b the valves she doesny have yhe money to replace them. Or the cam. Just wondering if there's anything else u can think of be for we check 100%

Well on our tips page it said about eh pin breaking in the camshaft gear and would throw it out of time which I think is your case. It seems this engine has an oiling problem that the pin breaks and of course the cam doesn't move but he gear will and all of them were on the driver's side. Being 16 rs old I think this may be the case maybe not but if it gets fire, fuel and there is compression it shold run unless it's an anti theft thing which you can look online on how to reset it.

Can you change the pins without removeing the cam or the head. Or should I take it off to check for a bent valve to be safe.

Just check the compression if you have a bent valve you'll know and I imagine the cam would have to come off as the pin would be broken inside the cam
