Not starting after mark d and injection swap

[bastianshaw]

swapped in new injectors and mark d 19lb injectors last night;car started idled roughly for a bit then i went driving, it smoothed out but the idle was still a little rough and CEL came on but then went out(no big deal) car ran great and was really fast. idle was still kinda shitty but i know it takes a while to learn, I also replaced the o2 sensor, so anyway I drove around for a while then came home turned of car and now it wont start. the battery got weak after turning the starter for awhile so im charging that now, it almost fired, but its doing that thing m20s do when they crank and SLOWLY start to run but its not catching and running I called mark d and he doesnt know.

anyone got ideas?

The first suspect would be intake leaks. Have a smoke test run.

Check the fuel injector harness for any breaks in the wires, I had the same issue and it ended up being a short in my harness

What's you mpg? It sounds like your car is getting way too much gas at idle and start up. I would clean the MAF to see if it helps.
