Have you done a fuel pressure test or any other testing ?
Is the security light on?

Have you scanned for codes?
Have you tested the injectors for pulsing?
It sounds like you never tested fuel pressure?
What year and engine?

an 05 2.2 it has lots of pressure in the line , all the way up to the rail when i turn the key to prime it , as for code reading , there is a problem there im still trying to figure out if the innova 3040 code reader is bad or every part in the car is bad , right now it shows 40 bad codes, but , it shows things like the temp is to high the next code is the temp is to low , or the idle is to high then the next is the idle is to low , weell so much for the obd reader is doesnt read most of the codes it droped . but the bigest one i can tell is it says it lost comunication with the bcm. could a wire be puled lose ?

So you dont know if the injectors are pulsing?

What is the lowest code number you have?
Check the plug on the BCM.

OK, my new noid light set came in today , tomorrow my new fuel pressure set comes in but it will probably be just like the noid light set , deluxe set , 10 lights , not a one of them fit the plug on my car , but it dosnt matter , the new fuel pump quit pumping fuel , it runs and all, but doesn't pump a drop of gas , a bit ago i painstakingly copied down every one of the codes , starting with po201 through 204 ( could have found out how true that is if one of the noid lights had worked ) ok here it goes. po201 through 204, p1137 and 1138, po106, po108, po462, po112 and po113, po122 and po123, po125, po131 throuigh 134, p1133,po137 and 138, po140 and 141, po171 and 172, p1171,p1134, p2ao1, po300,po420,po455, po496, po442, po446, po480, po502 and 503, po506 and 507 po530. will try and make a jumper lead today to fit one of the lights .
