Cranks wont start, Has compression, has spark, has Fuel up to the injectors, Has battery power, Plus i have a Car battery starter/jumper so definitely not that.
Does Run on starting fluid being sprayed in the intake, but only runs off of what i spray and does not stay on. I took the injectors out and manually tested and cleaned them all. 5/6 sprayed as expected, one not at all.
Have tried switching relays around with no luck, Fuel Pressure was tested and is good, took a spark plug out and grounded to test spark and indeed there is spark.

Could be a faulty replacement Crank Sensor?? might order a better quality one as i got the cheapest one.

Replaced:
-Crank Shaft position sensor
-BOTH Fuel Pumps And strainers
-Battery
-Spark Plugs
-airfilter/Cleaned MAF
-Fuel Pressure Regulator
-Fuel Filter
-Fuel Tank
-Cleaned numerous ground points


After reading forums i am very curious as to if a FAILED CRANK POSITION SENSOR WILL CUT OFF INJECTORS, OR SPARK, OR BOTH?? can someone please confirm this to me????

Thanks in advance.

 

You've done a lot of trouble shooting which is great compared to some of the "My car won't start, what can it be" questions.

If the car starts and runs on starter fluid then that confirms spark (at the right time) and compression. So I'd be concentrating on fueling.

If fuel pressure is good and injectors are (mostly good) then I'd be looking at injector signals. The looms can give problems with brittle/broken wires. You can check injector signals with a cheap set of Noid lights as a first step and then go hunting from there.

(The car would not run on starter fluid if the Crank Sensor had failed)

 

The nice kitty has a friend who is not acting so nice!

The crankshaft position sensor tells the ECU where the crank is in its rotation, and therefore when to shoot the injectors and fire the coils. So yes, it can cut off both if it is faulty. Often times the ckps operates intermittently which also really confuses the ECU. Sudden stalling, hard starting and very jerky acceleration can come up without warning, even when she's been running fine.

I concur with Brendan that since the engine runs from the starter fluid, the new ckps is probably fine.

How about water in the fuel? It will settle at the bottom of the tank and get pumped to the engine repeatedly as there is a fuel return line to the tank.

 

The # 5 large ECU controlled relay is controlled by the ECU and brings a source of power back into the ECU and importantly and separately this relay directly wired is also the 12 v sitting on top of the fuel injectors at all times.

The ECU provides the timed ground on the 6 individual ground returns to the ECU , this is your injector squirt

You can swap this relay and feel for it to click verifying it gets its correct command to close

M'Lady P. had a slice in the wiring to this relay for whatever reason

Kitty go vrum vrum

You only have one cat ?

Is there a back story to the problem? Was she running ok, and suddenly started doing this?
Water in the fuel is a definite possibility. As petrol floats on water, any water sinks to the bottom of the tank, and goes to the head of the queue for ingestion by the engine but for it to be totally dead, there must be quite a lot, as it will still run (like cr*p!) with moderate amounts.

 

yeah i suppose ill be tracing wires for abit now then, Thanks for the input, i think i agree its not the crank sensor. as i dont believe it could shut off only the injectors and not the spark.

 

Okay so then the CKPS is probably fine. Maybe my throttle thinks its wide open? took the tps out and cleaned it with no change, should start with it unhooked though from what i believe and it didnt so probably not that. As for water in the fuel tank there did used to be but i had a shop get a new tank from another car and put it in. so i can say 100% not. Its pretty much narrowed down to the injectors not going and im scared its gonna be difficult and expensive to get a ECU for the R as its different. and what if that is not the problem... arg. Can anything else make the injectors not fire... all at once, like a fail safe maybe? does anyone know if my voltage is to low would it still make spark but cut off fuel??

 

Back story unfortunately doesnt help much. former owner passed away car sat for a number of years, was parked in the spot i bought it from though, and apparently drove good before that. here is what it looked like

 

large # 5 ECU relay

Starting sag should not be below 11.4 volts
