2000 Sportage I just picked up with no start issue, it does have spark and will start and run if I spray starting fluid but has no injector pulse, have checked grounds, everything seems fine, getting power to injectors just no pulse. My question is will the engine spark without cam signal on this model, I was thinking it possibly had good crank signal but no cam signal and could cause this problem due to a waste spark style ignition system. Only one code for no TPS signal to TCM from ECM. TPS signal is good at ECM. Any help is appreciated.

I'm not going to be able to answer your question specifically as I don't have any first hand knowledge here but if you are getting a code for no signal from TPS, then that's your problem. Have you priced a new TP sensor?

Just start with the basics and then worry about the other stuff only if needed.
I find I overthink problems too much, especially electrical problems, and it turns out just to be a blown fuse.

I have proper TPS signal at the ECU. The code is p1555. I am going to check for continuity between the ECM and TCM. Should this model start without the TCM plugged in? No blown fuses, has proper power at ECU, I have went through the basics and read for hours using the search, there was a 7 page post from a guy who had the exact same problem as me but of course people rarely put the resolution on the post once the car is fixed

No joke. we spent 3 pages talking to a guy about his car misfiring constantly and getting poor fuel flow from one of his injectors and the diasnosis were all over the place. It was a very active post for like 3 days but then nothing. No resolution or response.

Have you tried PM-ing your guy?

Good Idea, I swapped the cam sensor for another used one today with no luck. I thought that was it after I unplugged the cam sensor and I still had spark. I cant find a good way to test the cam sensor like the crank sensor, i can put my multimeter on ac and see the crank sensor work but I can't see the cam sensor working with the same test as it doesn't operate the same way.

I tested continuity between the TCM and ECM wires, all good, also tested all the main sensors (TPS, CPS, power, ground, regulated power wires, test fired injectors) right from the ECU end of the harness and all seem to be reading/working properly. The only thing I haven't got a read on is either of the cam sensors that I have tried. Dangit I need a scope. Maybe I got a bad cam sensor from the junk yard? I have got to get this thing on the road tomorrow, anybody got any ideas?? Again thanks for the help.

I don't know if you came across these posts or not while searching, but here are a couple of links that might pertain to you.

Finally got it, found a chafed wire going to the CKP, fixed that then it would start but no power as if the timing was extremely retarded. I already pulled the timing cover off to check the cam alignment and to see if the key way on the crank was intact and had called it good, but since i had unbolted the crank pulley by the 10mm bolts and not the one in the center I mistook the notch for the pulley as the key way (it looks identical to a key way) after realizing I was down on compression I did a leak down test that showed the engine in perfect shape I knew something was up and took off the main crank bolt to find the key way destroyed from the last nut job that did the timing belt not tightening it properly, he did not tighten that bolt but ironically tightened the timing belt so tight you could play it like a gutiar......go figure. Thanks for the help.

If you do the timing belt on a sporty take the crank pulley off by the 10mm bolts not the 20mm one in the center so you don't have to worry if you tightened it good enough, plus you don't have the issue of holding the engine still trying to break it loose! I have read this has happened quite a few times, and can cause a bunch of misleading issues.

Glad to hear it worked out. I don't know that I was much help but at least you had some responses....
