injectors not firing 87 turbo 2 rtek7 2.1
 

I recently had a turbo swapped into my 86 sport now the injectors aren't firing. I am going to go get a noid light today to check the signal going to the brand new gsl-se injectors. Someone told me to change my afm and a couple people told me it was the ccfm in the rtek7,tune. I personally don't want to mess with the computer and can't find anyone locally who will so I'm asking if there is other things I can check other than grounds and what I've mentioned that I couldve missed the connections to the injectors are good and they are connected to the right harness plugs. The only codes I see are the prcv and the twin scroll selenoid in the computer.

Which injectors are not firing? All of them? How do you know that the injectors are the issue?

Also, how was this car swapped? If a turbo emissions (EM) harness (aka "engine harness") was used, one or more wire swaps could have been done wrong.

Another possibility is the fuel lines were hooked up backwards. This has happened on many turbo swapped cars since the hardline placement is different.

The only way I can get it to run is with someone turning it over while I spray carb cleaner into the throttle body. The primarys are,brand new gsl-se's and the gauge on the regulator reads 43# when I turn on the pump.

I used the stock n/a harness and the guy who did all the work isn't going to help me anymore. He cut and capped the wire for the knocksensor that went to my power steering.

I'm pretty sure the feul lines are good because it ran like crap right after the swap for a few days.

The guy who did the work has been on here for 10 yrs and claims to be the guy who ran a s5 tps sensor on his s4 first I don't doubt his knowledge he says its the ccfm on my rtek I don't really want to start messing with stuff without a little help from someone else. But I think its strange they just stopped working was hoping someone knew more about it than me could point me in,the right direction.

No shops will touch my car near Albany ny there afraid of rotarys. Is there a place on here to buy a technician in the area?

if you have a Fuel pressure gauge then you must have a different fuel setup than stock I assume.
Questions: which Engine is IN the car now?Series of engine and series of car?
As RotaryRocket88 said the Routing of the fuel lines is backwards from s4 to s5 and if you now have an s5 engine in the s4 car,it may read 43 at the Pressure gauge but that Is at the "end" of the fuel routing.So really you are trying to deliver fuel backwards and that won't work.
It may say 43 to the gauge but that doesn't necessarily mean that the fuel has gone through it's normal route and giving fuel to the injectors from PR to SEC TO Gauge.
It may just be getting To the gauge itself to give you a reading and going no further.
Take 5 minutes and go out and swap fuel Rubber lines At the Engine(up from the filter,and the return line..swap those 2 lines) and try that.

I have a 86 sport with a s4 turbo 2 block. Its funny you say that cause when he did the swap I sold my regulator and bought a sard. When he installed it he had to convert the rail back from a Cosmo setup that fed both rails equally cause the regulator was different. And the last person to touch the lines before it stopped firing has a s5. I'll try it tommorow night thank you for the knowledge.

I switched them today. No luck getting it started. Synapse motorsports told me to call back on wednesday hopefully I get an appointment soon
