I have a 99 4.0 that started sometimes and when I would use carb cleaner in the intake it would start always. I changed the fuel pump and now no fire at coil. I changed the coil, CPS, cap,rotor,plugs and still no fire. I have continuity at the front of the coil and the front of the CPS. Tried moving all the relays around in the power dist center but nothing. I lost please help??

BCDonny don't scare them all off.

With all the parts replaced you think it would fire off.

You say to get it running before you had to spray carb cleaner in it. Seems like a fuel delivery problem or extremely weak spark.

I would go back over your work and check your electrical connections. It worked before so you could assume the wiring and relays are still good.

Agree with joker go back over what you touched and make sure all connections are good

Not to be a smart ass but did you move the distributor when you changed the plug wires?
