Lately my truck has run fine....rpm gauge would bounce around then return to normal.... Today on my way home....rpm gause went crazy....from 5 to 0 (didn't think it was correspondending with the engine because the engine wasnt revving.

I was at a stoplight.... It shut off... Battery light was on...ignition locked up on me...couldn't start it...finally after trying long enough....it started....I'm so lost... Also horn isn't working either


Any help would be greatly appreciated

 

also no codes or check engine light

 

i just checked i have a code
P0340 (camshaft position sensor), what does that mean? can i just replace the sensor? or something tells me a relearn needs to be done

 

I would be willing to bet you need a distributor assembly. I had the same problem about 1 1/2 years ago and that was the culprit. I would guess that the horn is a separate issue.

 

A faulty ignition switch can cause erratic behavior of the I/P as well as no/hard start problems.

 

i couldve swore it was replaced during full tune up about 3 years ago. i know its ac delco. i had to bite the bullet and take it to a shop. i cant risk it just shutting off when im driving and potentially killing me lol

 

I'm wondering if there wasn't a way you could test the switch with a multi-meter. Im weak on components so unfortunately I wouldn't know how to do it, though when I get a chance I can look in the TSM.

 

according to meineke, its the camshaft sensor, crankshaft sensor and he recommended replacing the cap and rotor since in 6 years ive owned the truck i never have gotten it replaced. he tried getting me to get something other than delco , i think the brand was oe. i told him only ac delco cap and rotor and ill settle for oe sensors if he couldnt get delco

quote was 513 with tax and i found a 50 off coupon...gonna look up prices now

 

If they replace those sensors, make sure they do the Crank Relearn procedure. (This time I know I'm correct on the need for the relearn Swart and Les )

 

can the relearn only done with a tech 2 scanner? or is there another method
