Only cranks...

11-07-2008, 08:04 AM

my guess is if it is cracnking like normal u can stop thinking it is battery, starter, alternator..

it has to be either a flooding issue, fuel or spark.

unless you have cats that are completely plugged.. I have seen piston engines not start due to a plugged cat and once removed it fires right up.

start with the basics..

make sure u have fuel BEFORE and AFTER the filter
make sure u have fuel BEFORE and after the rail (check the return hose)

then make sure you have spark coming out the wires.
make sure u have no large vac leaks
make sure your sensors are ALL plugged in.(especially AFM)

once u do all of this then give us an update.

yeah im begining to think that too spooledupRacing

im begining to think that the plugs i put in are fouled now and same with the oil.. the oil is now smelling like gas.. i've done the Complex Unflooding Procedure(1986 - 91) from
http://rx7.com/techarticles_unfloodFC.html and it smells like gas and oil when i crank it. more like gas now. thats when the plugs aren't in.

so i put in another set of new plugs and i can feel that it cranks alot smoother and faster. i've tried starter fuild the car starts up only momentary.

this is what im begining to think what happened.. the car ran normal until the plugs became worn out and fouled.. and that so happens, after i get home..
so the next morning or when ever i try to start. bad plugs wont create spark and car floods itself due to excessive cranking. excessive cranking leads to oil and gas mixing and showing no compression sym'tems. not knowing the plugs are bad. im have to change my plugs every 6k or 8k miles.

so whats a good way to get all that fouled up oil out ? im running 10-40w conventional oil gtx castrol.

p.s. my cats new got about 4 months ago.

well even with fouled gas the car will run, I wouldnt worry about changing the oil until after u get it running again..

If you would like I can call u this evening and maybe talk u through a few procedurs to try and emilinate something.

let me know.

i'll pm you my cel #
i'll be outside today working on my fc... until about 3- 4pm PST

Change your oil, and pull start the car.

Rotary#10 · 11-08-2008, 04:15 PM

mmm im also thinking that my fuel pump strainer is clogged since gas was so high and i was so cheap... the strain has more than a few pieces of junk around it . so im going to replace it.

Rotary#10 · 11-11-2008, 04:28 PM

okie i just had my starter checked its good i cleaned up the contacts on the starter too.

Rotary#10 · 11-11-2008, 07:17 PM

had my battery changed too. turn over really quick but doesn't turn on.. now when it cranks it really sounds like its flooded. i got fuel at the fuel pump lines just right out of the tank and i got fuel after the filter in the lines..

TehMonkay · 11-11-2008, 08:10 PM

I voted defoul or replace plugs and pull start with fresh oil still.

Rotary#10 · 11-12-2008, 12:19 AM

mm there i tried the unflooding and when i checked the rag i used to cover the spark plug holes there were these little pieces of black carbon? gunk? ash ? on the rag. that shot out from Leading spark plug holes. any idea what it is ?

Phoenix7 · 11-12-2008, 12:22 AM

no....but have you done a real compression test yet? How bout the new plugs?

Rotary#10 · 11-12-2008, 12:35 AM

i have new plugs. do the poor mans compression test ? how ? i stand corrected as a noobie.
im going into the FSM and checking out the 'main relay' i thought u meant main fuse, i got them mixed with the main relay.

TehMonkay · 11-12-2008, 04:37 PM

Could be carbon, could be apex seal.

Rotary#10 · 11-12-2008, 06:12 PM

nah couldn't be apex seal. it could just be carbon build up.. whats a for sure way to know that the car will run after i change the oil..
i was thinking
-change the oil
-spray starter fuild in the intake after afm
- put about an ounce of marvel mysetery oil in the leading spark plug holes. it should start huh...

Phoenix7 · 11-12-2008, 06:14 PM

the main relay is at the firewall....in the corner between firewall and fender on the Driver's side.

It still won't start with the new spark plugs?
