No start, no click

[Ruiner]

so here's a weird one.

no start
no click
new battery
new starter
new cam sensor
Big 3 wiring

If u jump the starter relay it cranks, turns over, runs for a few seconds and shuts off. Its not the alarm, its not throwing a code yet.

Any other ideas? Maybe crank sensor?

Check your contacts behind your key. These knobs on the contacts wear off and all the sudden no start click nothing.

that wouldnt explain the once running, it just shuts off though

A sensor failure like the crank sensor would throw a code. Do you have any pending or current CELs?

Correct this is only the non start issue. Its possible you may have a few things going on.


Plus if the ignition contacts are warn off just like the start ones. I could see the truck shutting off.

no pending CELs, cleaned the contacts on the ignition, no luck

i feel like there should be a fuel smell with the amount of times I'm cranking it over by manually hitting the starter relay with power but I'm getting no gas smell

 

[gamefreakgc]

It has to be asked, did you change the wiring before the issue or because of the issue? The Big 3 involves changing some very important power and ground wires and if they are loose or dirty it can cause all sorts of issues. I've done it myself and chased some electrical gremlins linked to a dirty positive terminal post on the battery.

way prior, all are tight and free from corrosion. Could a short inside the starter cause issues with the relay but still allow it to bump over? I wouldn't think so. Though I did notice when getting tit turn over the EFI relay was getting warm.

so update, looks like it may have been a short that took out the relay, replaced it again and it cranks with the key. But no start just cranks. I replaced the EFI and CORS relay, but now I'm wondering if used the wrong type of relay. Do they both use the same?
