Truck starts and dies

[Psychopete]

LOL If one didn't know any better they might try to connect the battery terminal directly to the bottom left connection.

Since it's an '87, the OP will need to use that connection (self test out) instead of the CEL inside of the cab. There is no check engine light.

The "12VLED" indicates that a led (light emitting diode) can be used there to blink out the codes. You can optionally use a test light or analog volt meter. The pos and neg terms relate to the polarity of the wires from the light, or meter.

All the info you need on pulling codes:

I went to the junk yard and got a Map sensor installed it and the truck started up and ran like a top! cost me $7.00
Thanks to everyone for your help.

Good to hear you got the truck running right, I hope you didn't have to replace all the injectors.

I Did not replace the injectors, that was going to be expensive.......lol
