Hi, I bought my '88 GXL in July so I'm still a bit of a newbie but I recently did a fuel injector connector and injector change, fuel cutoff switch install, and the normal and typical emissions delete. Upon putting everything back together I found that my starter motor would crank over but the motor itself would not start. I think this is due to me being an idiot and pulling the two screws on the MAF out first instead of pulling the plug, then realizing my mistake and putting those two phillips heads back where they were supposed to be. Is that a logical assumption to why my motor isn't starting up? I don't think its the injectors or the new connectors as there is no way to wire an injector backwards seeing as how it's just a simple solenoid. As for the fuel cutoff switch, I verified that I had spliced the three prong switch into the correct wire on the fuel pump relay and also verified which wire goes to which prong. Thanks in advance for any help.

 

Have you verified it's getting fuel and spark? Does it sound like it wants to kick over or is it just turning over?

 

It's kicking over, I can hear it but it's like I'm not getting enough fuel which leads me to believe I've messed up my MAF.

 

What injectors did you swap in? OEM? Same impedance? Also double check that you didn't leave any rags or paper towels in the air plenums or throttle body. Pulled spark plugs? What did they look like? Try holding the AFM slightly open when cranking see if that changes anything. Double checked wiring at fuel pump? How did you wire it? Verified that its running? With the key on run, and holding open the afm door, you should be able to hear fuel moving through the system.

 

It kills me when people get a car and do an emissions delete and then the car runs terrible or will not start. Remkving the emissions equipment can cause a poor running condition and no power is gained. Yes you simplify the engine bay, but you are removing stuff that helps with hot and cold starts, ease of throttle closing, deceleration control, etc.

 

Injectors are OEM spec with the same impedence but with EV6 connectors instead of the EV1 of the originals. Gonna try holding the MAF open and see if that does anything.

 

Agreed wholeheartedly.

Also, OP, the term "typical emissions delete" could mean many things to many people in terms of what was done and how it was done. What guide did you follow? As mazdaverx713b said, removing this is much easier to cause more issues than it helps (and it doesn't really help any, imho.) Why did you pull the screws out on the MAF? It seems like you were tweaking things that didn't serve much purpose to be tweaked.

I would break out the FSM and a multi meter and check the maf's readings, and go over whatever you removed with the "emissions delete" and likely put it all back on (if it were my car personally.) If the car ran before, the only things that could have been effected are the things you touched. Why did you put in a fuel cutoff switch? If I were you I would just return everything to stock and work your way from there.

Doing many modifications at a time makes troubleshooting a significant pain when you don't know what could have caused the issue you are experiencing.

 

Emissions delete as in removal of the vacuum harness, ACV, Sub-zero, and EGR, definitely never removing the BAC. Fuel Cutoff switch to completely eliminate a chance of flooding in my motor.

 

I cant say that your maf is messed up for sure, I would use a multimeter and check it. But i have personally broke one when i took the screws off the connector years ago. I had to grab another one from the bone yard this was for an MX3 not rx7, but they use a trap door maf too.
