04 FM Turbo Miata (not MSM) running 9 psi & 550cc injectors. Everything was working great. No startup issues, etc.

Then yesterday, I was driving the car and an intercooler pipe popped off. Obviously, the car shut off. I connected everything back together and drove the car home.

Since then, starting the car requires a few seconds of cranking. It used to startup immediately. Now it cranks over about 10 times before. Also, there's a slight squeak with one of the belts of pulleys.

Suggestions on what's wrong? I'm running the XEDE. AFR at idle and cruise is stoich, and about 11:1-12.5:1 under boost.

Anyone else have this or a similar issue? I really need to figure out what went wrong and how to fix it. This is my only vehicle.

Does it still boost the same as before...

I got nothing other than check your couplers.

It still boosts the same. Once the car is started, besides the noise of the belt/pulley, it drives the same.

check belt tension, if need be tighten. belt problem solved.


as far as the cranking issue, can you datalog with the XEDE and maybe show us whats going on while cranking?

ps you seem to be running a tad on the lean side in boost if you go to 12.5 (assuming you dont mean boost as in 110kpa crossover to heavy boost)...
besides that im no help.

I'll check the tensioner. Could you explain to me how to datalog while cranking the car? Tuning is new to me so I'm playing the conservative game.

I ran by Autozone today and had the following codes:
P0300 (expected with the XEDE for changing stock timing)
P0340 (camshaft position sensor circuit malfunction)
P0132 (heated oxygen sensor HO2S (RF) Circuit High Input
