Hi All.
First of all, im new to fordorums... soo HI!!
anyways...
I have a 302 Windsor EFI, ive had the upper intake manifold, and the tappet covers off, ive re-assembled, NOW it wont start??
The motor's cranking over easily, just not starting.
Ive double checked the firing order... - when it was connected the 'wrong' way.. it actually starts tho?????? But i have a backfire, then really rough idle??
With the correct order connected... the engine cranks, but no start????

Does anyone have any idead what it could be????

Cheers

G'day,
be carefull, there are two firing orders. (1-3-7-2-6-5-4-8) and (1-5-4-2-6-3-7-8).

Yours should be the first. If it pops and farts then you are 180 degree's out. If you get it wrong, it should still run, but will have an ugly miss.

Cheers
Jas

tried either... still wont start.
I havent got anyone here at the moment to check for spark???
Might go n buy a new dizzy cap anyways??

I've been told the engines outta an early 90's Mustang?? But when i had to get a new air con compressor, it was a f100???????

they dont have different firing orders do they?

No the EFI 5.0 runs the later firing order..also known as 351 order.
