Slow Starting

[jd21]

My 91 gsx is still really slow to start, it cranks fine just takes about 30 seconds to start no matter if its cold or warm. The timing is dead one, new plugs and wires, new coolant temp sensor, new battery, compression is 150-155 on all 4. I cant find any vaccum leaks i just replaced the injector seals, it has a new 255 in it i just cant figure this out pls help

Checked the fuel pressure? Is it slow to build?

Guaranteed its the fuel filter, have you checked? just remove it and try and blow through it.

 

[jpmxrider489]

Do you have a AFPR with the 255? It can be a clogged filter.

 

[jd21]

Its a new fuel filter and stock fpr i need to get a pressure tester and check the fuel pressure

 

[zcoh2gdsm]

get an afpr, the 255 will soon over power the stock fpr and cause it to fail.

get an afpr, the 255 will soon over power the stock fpr and cause it to fail.

+1 on that. its only a matter of time before it goes.

is the battery charged?

 

[jd21]

the battery is new, its not thats its cranking slowly it sounds really strong is just take about 30 seconds to start

It could be flooding the plugs try a new ngk number 7 plug its hotter and might give you the spark you need to compensate for the 255.
