The other day my car wouldn't start. It would get really close to cranking but wouldn't start, basically it was making an rrr-rrr sound. I did get it to work today but I think was luck and alot of praying. I'm pretty sure its not the battery. I got a check engine light a few weeks ago with numbers. p1237-p1240.Cyl.1,2,3,4-Fuel Inj.Circ. Open Circ.
the engine light went away right after I got numbers at autozone. I'm guessing bad wires. I want to make sure this is a correct diagnosis and if I should check for anything else such as a starter or alternator. Also, I'm still a newbie(looking to learn) so If you could point me in the direction of a DIY for checking and changing the wires that would be very helpful, I've already tried a search to no avail. Thanks and sorry for the newbie trouble.

 

Saw such a problem on a 30v recently and it was the crank position sensor. Wires can go bad but it's almost unheard of on these cars. Check your plugs or just replace them - they're very inexpensive. Clean all of your electrical connectors with contact cleaner too. See if that helps.

As for changing wires, if you want to, get a new set and remove the beauty covers on your dngine. The wires are right there. changing them is just a matter of looking at them and swapping them.
