I have a 1984 mustang 5.0 5- Speed and Im having a problem starting the car.... The car started then idled good... then died... then sometimes wont even start..... It has a performer 600 edelbrock on it.... The guy i bought it from said it has a bad accelerator pump in it but i thought that would just cause the car to bog.... I looked at the firing order and everything.... The car has 123000 miles on it but was rebuilt at 100000 and it says to use the 351 W firing order but they are the same..... I dont know what to do next..... Rebuild carb? It smells like its getting gas.... and gas is in the fuel filter.... and smell it in carb... but then pulled out one plug and looked dry? Help please.

IS your timing correct? There are 2 firing orders for the 5.0, here is a good diagram for them. Get a Holley 600, 4160 or 4150, they are much easier to tune and work with IMO Hope this helps out a little, I dont know alot about cars yet but I am slowly learning. Someone on this forum will have some great answers for you, probably better than mine.



EDIT: The 351W firing order is also the 5.0 HO firing order, I believe

when it won't start check for fuel and or spark..to narrow it down to one of the two

its getting gas and spark.... I can smell gas... and i see it in carb and in fuel filter....

It couldnt be accelerator pump could it?

verificaton is done with test equipment, not the eyes and nose...do you even know how to verify such??

Underhizzle

I mean what should i do now... that i have spark? .... and might have gas.

mjr46

spray some spray start in the carb and see if it'll briefly fire up

Underhizzle

Yeah but thatll probably do what it did before... just start idle then stall..

then it is a fuel issue....pull the feed line to the carb and run it into a clean milk jug and crank the motor and see if it spits fuel out of the line at a moderate rate...sounds like you have a fuel issue
