last night i got the car started after a rebuild as you guys know, this morning i finished putting it all back together and went to start it and nothing no spark so i checked my fuses and control unit engine #32 and #34 keeps popping, i hate electrical with a passion so i was never good with it

You check for relays? piched wires? COMPRESSION TEST?????

compression test on a rebuild motor? really? how would anything to do with engine internals cause fuses to blow?

lol srry got caught up with another but check all grounds

are your coil packs grounded?

2nd of pinched harness, possibly near engine/trans mating

i know its insluting but the ground on top of the valve cover? but it does seem like you got a short to ground somewhere.

yeahs sounds like a short or something. pinched wires is a good guess as stated.

Bigger fuses = done deal.

(lol j/k)

On a more serious note, the process is something like this (proceed on the list as far as necessary):

- Check for obvious shorts especially with regards to the last service performed
- Procure an accurate wiring diagram (and know how to read it)
- Unplug all devices on the circuit that are reasonably accessible to do so
- Check for presence of short (circuit resistance to ground) or install new fuse
- If still shorted there is a wiring fault which will require more investigation
- If no more short, plug devices back in 1 by 1, when it blows = bingo.

- If no more short, plug devices back in 1 by 1, when it blows = bingo.

Put a ohm meter across the load side of the fuse and ground. When you plug in the pinched device, the ohms drop to zero.

Yeah, I explained that in the step above:
- Check for presence of short (circuit resistance to ground) or install new fuse

I was just being lazy and didn't include the "or" statement for both steps. But you caught me...lol.

its all good, turns out my buddy pinched the wire and grounded it out -.- and now its still being a bitch and dont wanna start -.- dont get why tho, everything is hooked up right, went over it so many times and not having luck, i wonder if the gas is too old (5 months old) and wont ignite right, we did drain some in a cup and see how it lit, it wasnt really that blue like normal. im kinda outta ideas here

If you think it's the gas you can try adding an octane boost to it.
Do you have spark now?
Fuel pressure?
Are your injectors new/clean or did they gum up sitting for 5 months?

depending on what you pinched, you may have blown the ignition switch. is the motor turning over?

i gave up and sent it to the shop, im over messing with it, but i'll post what the outcome is, im sure its something stupid

hopefully the wallet doesnt get dried out too bad. electrical can add up real fast.

the electrical has been taken care of, i have spark, but still no start camshaft sensor works idk just wondering if its an computer thing
