Ive got a jeep cherokee 1993. Just did a tune up, new plugs, wires, distributor cap and rotor, Oil change, the works. It ran fine before just a little preventive maintenance. Well now after its done, it refuses to start. Will continue to crank but thats all. I am able to hear the fuel pump and I get a spark from the coil. I've triple checked the firing order and know it by heart now. Anything you can suggest would be great

Check the fuel pressure and comeback with the readings. Inspect the auto shutdown relay-this one powers coil/pump and injector/s.

Ive got plenty of fuel pressure. Dont have a gauge but I unhooked the line. And it spurted out fuel. Then reconnected. Turned car back on. Fuel pump ran and again spurted out fuel. And its not the relay. Anything else?

I understand its got a lot of fuel pressure but is it the correct pressure, you need a pressure gauge. EFI is very picky on its pressure. Also crank engine over while listening to the injector/s are they pulsing-

Check your rotor again. And the inside of your dist. Cap. Loose grounds at the firewall and block near dist. Can cause start problems.
