i got my chevy p/u to start with the help of starting fluid, but it will only run for bout 3 sec. then shuts off like it's not getting any gas. It is a v-6 tbi. Would cleaning the tbi help it? How do i do that? Any help appreciated. thanks!

Sounds like a fuel problem. Check the fuel pressure, injectors and their wiring and fuel filter.

Not to sound dumb, but it does have gas in the tank, right? How old is the gas?

Check that there is gas, that the fuel filter is clean (just replace it) and that the fuel pump is working.

The p/u started and ran good for several minutes then i would turn it off and restart and it would. Now it will crank but not start, i checked fuel filter, i can hear fuel pump kick-in. Would a bad ignition coil do that?

[quote="00Beast"]The engine does not always end with the #1 cylinder @ TDC. It ends wherever the engine comes to a stop at. The easiest way to get it to #1 TDC is to take a paper towel or a rag and roll it up, stick it into the plug hole w/ the plug out and the engine disabled so it won't start, and turn the crank with a wrench on the bolt on the balancer until the compression forces the rag out.

Also, when the proper timing is set, the rotor points at the post a few degrees before TDC, as that is what timing advance is. [/quo How do you set the timing?
