Starting problems

my 2003 silverado will not start

Postby racebluesilverado [OP] » Aug 12 2012, 3:31am

please help.....i have a 2003 silverado when i turn the key on i have power to everything but truck does nothing when i attempt to start....i have replaced the ignition, starter and battery. it was doin it now and again for a while but i would let the truck sit and it would start right up. but now it will not start at all. the abs light, emergency brake light and serviceengine light come on. before when i would let it sit and then it would start, the lights would pop up while driving truck wouldnt stall or lose power but once i turned it off i still had power but no start. i hear nothing when i turn the key no starter clicking or fuel pump coming on. it was seeming to do it while i had the air on. please help i really need the truck for work

Youll need to bust out a multimeter and verify your getting power to the starter...report back

An open wire can have several factors on how and when it connects the circuit. Temperature causes expansion and contraction that can connect and disconnect a circuit...vibrations obviously move the wire around. Poor grounds, rusted wires, etc... You need to trace the power from the starter relay, ignition, and to the starter...

hey man i traced all the wires back and i can not find any thing wrong with the wires... i pulled the starter off took it to get it checked....it was bad and they gave me a new one....i put it on and it still did not fix my problem.....i pulled the cover off the pcm and started messing with wires got the truck to start a couple times but after i shut it off would not start again....what wire from the pcm goes to the starter....i think the reason the starter already went up is because i tryed jumpin it and it arched and melted the metal piece on end to the solinoid...truck is really puzzling me but do not want a shop to rape me cause i kno its a simple fix just have to find it
