Engine startup

I fixed my electrical problem so the starter engages, but the engine won't start. Any easy to overlook suggestions? 1996 mustang

Is the engine cranking strong now? If it is it's probably the fuel pump, it crapped out at some point and is not sending any fuel to your engine. Turn on the car with the everything off like the heater or radio but without starting the engine and try to listen for the fuel pump turning on or not.

You need three things to start your engine. Air, fuel, and spark. You are getting air so next would be check fuel and spark. You can disconnect your fuel injection and pull a wire off of a plug and stick a screw driver in it and hold it just barely away from your engine block and see of it sparks and if it doesn't then thats your problem and if it doesn't then its your fuel system

Can't you also check the spark with the distributor? Or in this case the COP or coil pack? Haven't tried it yet but with my 66 I just take a plug off the distributor cap and check the spark that way

The fuel system will always fail before the electrical system unless something weird has happened. That's what I've always been told.

This is the fuel filter, does it look like it may be the problem?

Also to see if the fuel pump works can I just turn it on to see if gas squirts out not that the filter is off?

You can put a fitting on your fuel rail and attach a hose to it and squirt it in a bottle

Ok so I turned in the car and fuel went thru where the fuel filter was. Does this mean I just had a bad filter?

possibly, basically all that eliminates right now is your pump. once you get a new filter in there try it again, after that is your injectors. unless there is a blockage in the lines somewhere. for which you could hook up a fuel rail pressure sensor and turn the key to on and see if you get pressure

Yeah hooking up a fuel pressure sensor is a good idea, then you would know if its not getting fuel to the engine. If you are getting fuel then it has to be a spark problem.

You can probably barrow one from a autoparts store

I got the fuel sensor and everything checks out. This leads me to believe its a spark plug issue. How would I test the various components responsible for igniting the gas.

Well take a plug wire off stick a screw driver in it and hold it about a 1/4 inch away from the block and see if it sparks of it does then you know it has to be timing and if you dont get a spark make sure you have a good connection to spark plug wire and try again and make sure your not to far away from the block

You cant change the timing on a coil pack... So most likely its the plugs or the coil pack

I tested the resistances on my coil pack according to my repair manual and they were all off according to the book. Would this keep the spark plugs from igniting?

Yeah if they are off that means the coil pack is no good, you need a new one. Just buy the oem one from Ford it's more expensive than the aftermarket ones but from what I have heard those aftermarket ones only last around a year anyway.

Check your crank and cam position sensors, if they go out completely it can prevent spark. Also, check the sender for your coil pack.

You were right, the cam position sensor was loose.

No, I have to adjust the timing. Other than that she's fine.

How are you adjusting timing? I didn't think the timing was adjustable on our cars O.o?

Straight to the timing chain. I'm thinking I knocked it out of sync when I changed my head gaskets.

If it was off you would have a hole in your piston or a busted valve

There shouldn't be any way to be anywhere near close to the timing chain while doing head gaskets unless you took the sprockets and chain off the cam and crank..

If you messed with the lifters or anything, they may need adjusted, and check the wiring on the cam and crank sensors, if the cam sensor was loose, chances are its been compromised and needs replaced.

My biggest suggestion is to get a haynes or helms manual if you don't already have one, they're a life saver.
If you can, get a vid of what the car does when you fire it up now, any sounds or odditys about it.

Not much, school and stuff. But as to what's wrong it looks like the cylinders aren't firing in order. It'll almost start but the engine shake really bad and won't fully start.
