Dies after starting

Can the fuel pump relay and pressure regulator be tested on the truck?

You can test the coolant temp sensor it could be bad causing the ecm to give the engine more fuel than it needs. The sensor screws into the intake manifold, on the front passenger side, by the thermostat housing. Coolant sensor approximate resistance specifications: 177 ohms @ 212 deg. F. or 100 deg. C.
241 ohms @ 194 deg. F. or 90 deg. C.
332 ohms @ 176 deg. F. or 80 deg. C.
467 ohms @ 158 deg. F. or 70 deg. C.
667 ohms @ 140 deg. F. or 60 deg. C.
973 ohms @ 122 deg. F. or 50 deg. C.
1188 ohms @ 113 deg. F. or 45 deg. C.
1459 ohms @ 104 deg. F. or 40 deg. C.
1802 ohms @ 95 deg. F. or 35 deg. C.
2238 ohms @ 86 deg. F. or 30 deg. C.
 2796 ohms @ 77 deg. F. or 25 deg. C.
3520 ohms @ 68 deg. F. or 20 deg. C.
4450 ohms @ 59 deg. F. or 15 deg. C.
5670 ohms @ 50 deg. F. or 10 deg. C.
7280 ohms @ 41 deg. F. or 5 deg. C.
9420 ohms @ 32 deg. F. or 0 deg. C.
 12300 ohms @ 23 deg. F. or -5 deg. C.
16180 ohms @ 14 deg. F. or -10 deg. C.
21450 ohms @ 5 deg. F. or -15 deg. C.
28680 ohms @ -4 deg. F. or -20 deg. C.
52700 ohms @ -22 deg. F. or -30 deg. C.
100700 ohms @ -40 deg. F. or -40 deg. C

According to the factory manual I have my truck does not have a hot fuel module.

[Irish_Alley]

Never heard of one of those

Coolant temp sensor is NOT a hot fuel module...

It tells the computer what temp the coolant is so the computer knows how much fuel it needs to spray...

If the computer thinks it's -40* it will flood your engine....

Just an update to my issue.Replaced the the plugs,wires,cap,rotor,ignition mod,coolant sensor and fuel pump.The latter two after testing had determined failures,the rest because it was needed.Truck is running like a top and is once again a pleasure to drive.I do have one more question.With out the use of a tach what is the best way to check and monitor the idle.Thanks

With out the use of a tach what is the best way to check and monitor the idle.Thanks   

The answer is in your question, you can get a tach for $30 and it is easy to hook up.
