99 keeps flooding and wont start - 2.5L

Hi there. Update on progress
Installed a set of plugs that are one heat range hotter. Car took 3 attempts before it started. I let it run for 20 min to warn up really well and clear out any residual fuel. Went to back it out of the garage. It stalled right away. Then hard to start. Once running again tried to back out again. It did the same thing. Shut down as soon as there was any load on the engine. Also tried to move it forward. Same issue. Very hard to start. Lots of spitting and sputtering then suddenly it catches and runs very smooth. Sometimes when it just fires up after a hard start if I let it go down to idle to quick it also quits running. When I say it quits it is a quick shut down. No spitting or spurting just quits. Looking for any ideas.. thanks in advance

How is the fuel pressure? Have you measured it?

Dang! No power sounds like the timing is not lined up right to me. Maybe its just a lot of air in the fuel but after running for 20 minutes, seems like there would be no air in the fuel system. If she ran fine before you changed the IMS, there should be no new issues. You didn't jump a tooth? You re checked any wires you took loose for the IMS project? Hmmmmmmm...........

I do not have a fuel pressure gauge - but will ask a buddy if he has one.
The way the car revs so freely when in neutral I really don't suspect a fuel pressure issue but one never knows

When the car does catch and fires up it sounds beautiful. Will sit at idle nice - no hunting no spitting or sputtering, Can be freely revved up and can hold at any RPM and is steady.

Can you actually slip one tooth on a sprocket and still have a smooth running car?

How does one check to see if all the chains are in the correct position? - We locked all the chains and the pulley before we removed the old bearing. Removed all the locks after the install was complete.

Thanks for the ideas
Keep them coming
Appreciate the Help.

When we did the work we also replaced the AOS - Is there a chance that a bad AOS could cause these issues. Improperly installation cause these problems.

I have looked at the connections as best I can - on the top the connecting pipe had a broken clamp that went onto the top of the AOS - I fixed it up and seems to be holding well. If i wiggle the pipe slightly it makes no difference to how the car is running.

Fired up the car today - started great but once warmed up it would not idle properly and was tough to start.

Borrowed a OBD code reader from a buddy
Had 3 codes in - 2 were related to O2 sensors
1 was the crank sensor

Cleared codes - Ran car and let it quit a couple times - No CEL came on
Put OBD on again - Crank sensor failure code.

Did a little reading on Pelican site to see how tough it is to change and if it could be done with trany in - Seems it can be changed without trany removal - Just a bit of a crap job.

A few of the people who wrote in about the sensor failure seem to be having the same issues as I have - a couple were right after clutch changes also.

Will order in a new one tomorrow and may take a night this week and put it in.

Hope this is it.

Again - Thanks for all the help and the push to get a code reader.

Will be purchasing one of my own soon.
