I suspect a Injector leak. Slow starting now with Hissing primary injector. I think the fuel pressure is not building up on the good injector and the other injector flooding the rotor. the deflood wont work with this i have found out because the good injector rotor has very little pressure because of the bad injector. I found a few laying around. they read 195500-1350s denso, On the plug part on the side it reads 530.

the ones that came out of my primary were 732s are these the correct injectors?

I took a look at the Injector chart NA turbo and what year used what. And i dont see what car 732's go to! my injectors are 732's primary. Im looking at the 88 NA chart its calling for 460s. and 530 and 732s are not even listed

84-85 13B NA, low square center, 680cc, orange, 195500-0900
86-87 13B NA, low square center, 460cc, red, 195500-1350
86-87 13B Turbo, low square center, 550cc, tan, 195500-1370
88 13B NA, high square offset, 460cc, purple, 195500-1350
88 13B Turbo, high square offset, 550cc, purple, 195500-1370
89-91 13B NA, high oval center, 460cc, red, 195500-2010
89-91 13B Turbo, high oval center, 550cc, purple, 195500-2020


So this would be Me 88 13B NA, high square offset, 460cc, purple, 195500-1350
Is that calling for primary and secondary injectors should have 460s in them?
my car has 732 Do i have the wrong injectors? I dont see a listing for 732

Still waiting on some help here, Am i reading the wrong Numbers on the Injector? i see the part Number and then on the plug says 732. Do they not make 732cc injectors. If not then i am reading the wrong number. where would it say what cc the injectors are?

Why are you assuming that 530 and 732 = the cc of the injector? It's probably a mold number or something from whenever the injectors were made.

If both sets of injectors are the same color & have the same notch offset, they're interchangeable. We're talking NA, right? '88 high impedence 460cc injectors are red, not purple. Purple would be 550cc turbo injectors.

Im just reading off the chart. says should be purple. But does not matter anyways. Its gotta be 460s or else it would hardly run. yes 88na. Injectors are not flooding. Car still wont start cold. Will start now if i Pump the gas.. checkin for vac leaks. dont see any so far

The colors listed in the FAQ aren't 100% right. I have 3 sets of red, high impedence 460cc injectors & a set of purple, low imp. 550cc injectors. The FAQ says they should be purple and tan, but they're not. Go by PN & the offset.
