The BS does not end AHHHHHH! Advice needed.

OK after installing the transmission and dealing with the transmission fill plug from h3ll. I have had high idle like 1500 to 2000 rpm. The Z is not my DD. I drove it three time since I had it back intact. The first time I took it for ride it cut back twice. I got to my buddies home and when I got on the gas she cut off and did not crank again for 20 mins. When it crank back up still constent high idle. Drove it home. Drove it saturday night still high idle. Checked all vacc lines everything intact. Today I go out to find why there is high idle but now the car will not crank. It tunrs over but nothing. I noticed the ground wire on the starter looked a little crappy. Is there something I may have missed?

She cranked after the post

you sure your not flooding the cylinders? bad injector o-rings could equal internal carnage

[300freekzx]

I do not think that could be the problem as all of my injectors and o-rings are good. The crazy thing is I went back outside, cranked the car and let it sit for 10 mins to warm up (the idle actually dropped to normal). Then, I reved to the motor slowly with no problem (as if I was slowly driving). Next, I reved it quickly like I was pulling off fast then the problem occurred, and it shut off right at 4k rpm. I cranked her up again did the same thing she cut out again at 4k rpm. Now she will not crank. I do not want to keep repeating this as it can't be good. I noticed that there is a lil more noise coming from the left exhaust like the test pipe might not be fully tightened to the header. Could loss of backpressure cause this? There is alos a lil bit of puttering coming from the left muffler. Do you guys think something could have gotten into the exhaust sys whille I had it down doing the transmission pull? For those that are woundering why I did the transmission pull here is why......http://zclub.nicoclub.com/zerothread/475844 I did not have this problem until I reinstalled the everything please help shed some light on this.

Well went out in the cold to try and crank her no crank. I only heard the fuel pump pressurized once while I was out there. Maybe the death of a fuel pump? IDK at this point.

update I tapped on the fuel filter she cranked up but died right out. Tapped on the fuel filter again but no avail. I will pull the fuel filter later and see if it is dirty city going on.

Check your CAS connector. Perhaps its corroded and making an intermittent connection. It's one of the few that will cause it to just quit. Others would be the PTU, power/ground to the ECU or fuel pump.

Fuel system is fine. I am getting full pressure the filter has the gas so clean if it was drinkable you could drink it. This is aggravating! I can hear the starter grinding from trying to crank (I know it is not a good Idea so I have stop cranking for the moment. The timing belt is intact (checked again). Next I am going to the MAF. What is the most effective way to check it? I will check those also buddy.

The manual in the EF&EC section, starting on P178 or so shows how to test most all of the components.

Do you by chance still have the original finned silver PTU? The sign of it starting to fail is it will run for a while and quit until at some point it won't start at all.

A failed MAF will still allow the engine to run, just not well and maybe 3000 RPM max

Ok she cranked just not but I think there is blockage in the exhaust. I thought I had all of the water out of it before I reinstalled the system howevery I do not not. The car was run for about ten mins something told to look under the car both sides are puttering and I found a hole in the pipe behind the cat on the left side with a nice size puddle of freaken water coming out. I know it was pretty stupid of me to leave my exhaust out in the rain with nothing covering it. I will drop the exhaust and check it out on monday. If you guys think I am going over board let me know. I will still check the MAF PTU ands CAS.

[300freekzx]

Ok I found the problem. The connector to the CAS is on the fritz. The connecter controls the fuel system some how? The reason I ask is when turn the key to the on position and wiggle the wire I can hear fuel system kick on and off. When crank it I can go under the hood move the wire and the car shuts off. However, why would this cause the car to stall at higher rpms? Could it still be clogged exhaust?

[300freekzx]

Problem fixed! It was the CAS connector was corroded and the TPS wire was broken and corroded. Cleaned both and I rebuilt the TPS connector a lil solder and gold plated connetors FTW! Plan to purchase EFI harness in the near furture.
