No start... except with starting fluid.
Hello! New member here. I have just acquired a 1998 Discovery 1. It is a GEMS gasoline V8. I'm having a no start issue with it. The truck will start and run... but only with starting fluid. It won't start on it's own. Has spark during cranking. Fuel pump runs and has 40 psi at fuel rail. Cranks strong and long for as long as I turn the key... but won't cough or fire a single cylinder. But!... if I feed it a little starting fluid (ether) it fires up and runs just fine. Just got some new fuel in it (mixed with old stuff) but still does it. Once the truck is running, it runs great. Almost like the fuel injectors are not firing... But only during cranking???Any Ideas? Or anyone had this issue. Anyways, this is my first Land Rover. First British car. I'm excited! Thanks for your help

Hi! Thanks for the reply. So... it has no codes and the check engine light is not on. I had originally thought Crank Position Sensor... but i have swapped that out already. Tested the one that had been in there when I got it, and it seems to work fine as well. Has spark and runs fine once started so I don't think it is the cps. My 98 does not have a cam sensor. Does yours start with some spray in the intake as well?

Could be... my temp sensor works during driving (shows an accurate temp). Could the sensor read bad during start up and then start reading better when it is running? My experience with failure on temp sensors is they read cold (like -40)... so in my mind it would give it more gas during start up if that was the case. I am new to Land Rovers so I don't know if that is how they work yet.

I'm also new to LR but can tell you that I have seen plenty of coolant temp sensors fail "closed" and provide a lower resistance value which indicate a warm vehicle. I have read that my 04 D2 lets the ECU approximate the coolant temp as indicated on the gauge and earlier models do not. In my experience there is usually a separate sensor for each function. One for the ECU and one for the gauge. Since mine doesn't work this way, maybe yours does.

You may be able to disconnect the coolant temp sensor to simulate high resistance (aka cold motor) and see if the ECU richens the mixture and the vehicle starts. ODBII may not be happy with this decision and may freak out however so be prepared for code resetting. This new fangled stuff is out of my wheelhouse but this is where my logic leads me. Someone else may have better insight on whether or not disconnecting the CTS is a wise descision.
