Can anyone tell me which computer is the correct one for my pickup, by the V.I.N. What is the cost of a computer for these trucks? 1B7HC16Y1RS******

It has a 5.2 engine, air, pw. pb. ps. p. mirrors, Auto Trans, 2 wheel drive.

Just put on new cap & rotor, crank position sensor, still no fire up.

Coil checks out good injectors ar ticking, I'm at a loss here as to where to go next. Need some help here if some one has an answer for me.

I' had the engine completly rebuilt 15,00 miles ago new rad, Trans was done 53,000 miles ago, new shocks last 6 months, brakes 3 months ago new calipers. New Michelin Tires 10,000 miles on them 235 x 85 x 16. Reason for the Tires wanted a good set of rubber under the Truck.

Anyway need some advice on this if you will, thanks in advance.

 

Are you getting spark?

 

I just got off the phone with my mechanic, no spark. He says that it is just as though you are trying to start it with computer unpluged.

 

If you are getting injector pulse, but, no spark, and the coil is known to be good, probably time for a new crank sensor. If your mechanic has a good scanner, should be able to read the data stream and verify it the PCM is getting crank signal or not.

 

Yes sir a new crank sensor was also put on, with no reading.

 

HeyYou

Just came back from the Garage. not getting a reading to the PCM from the Crank Sensor.

Once again the following new parts were put on the Truck.

Pickup in Distributor
Cap & Rotor
Crank Sensor

Coil is good & Injectors are Ticking. Still no fire up.??????????????????????????? Help

 

Maybe try another crank sensor? Check to see if you are getting signal from the crank sensor by checking voltage at the plug. If you are then id say you got a short in the harness, and i would bypass the harness with some new wire and tap back into the harness just before the ecm plug.

 

Unscrew the o2 sensor from the cat/pipe and see what it does. Has fuel pressure been checked ? Have the relays in the PDC been checked?

 

You really should start reading this post before you respond....

 

What did I miss ACE????????????
