Idk much about this site but I need help. I have a 1990 jeep cherokee lerado that won't start. I have spark from my coil to my distributor and spark to my plugs. I'm getting gas no problem. I replaced the pickup in the disributor replaced the ecm and crank sensor and so far nothing has help it just cranks and cranks. Need help ASAP.

 

Did the '90 have a NSS? Pretty sure they do.. Might be that. Tried starting in Neutral?

 

Getting spark so its not nss. Getting fuel and getting proper fuel pressure two different things.

 

I don't have a gage to check pressure but when I have the key on and and press on the check valve on the fuel rail it shoots a stream out 2 or three foot so I feel like it has plety of pressure. 3 week it's been down. I had a small eletrical short in the ****ty wiering that some one had for a eletrical fan. And it burnt the ecm plug so that's the reason I replaced the ecm and plug. So I'm just wondering G if it back fed and got anything else's like computer or what not. I'm not to familiar on the sensors and stuff on the veichle.
