Distributor sensor. sputtered doesn't match running. Also by bypassing the fuel relay you can have caused other issues as the fuel is linked to the igniti...

Oh sorry man, I misread your last post. Okay so next step would be to confirm spark.

Edit: if you haven't touched anything in the engine bay I guess it's safe to assume spark is still fine from the last time you checked it

cr80442

That's all good, when I first got it I tried starting it with spray and it ran for a 2 seconds just on starter spray. I'm fairly sure it gets spark. I'll still check tho what's the best way to do that? Never checked spark on a car only on dirt bikes and stuff

Just pull a plug and attach lead to it and ground the plug on something on the body

The car wont start with it unplugged did you check the relay on shocky tower

volvo1975

Check the relay.. may be on radiator bottle side of it

cr80442

The car does get spark, I don't see any relay near the rad bottle

volvo1975

Its the radio/ fuel injector relay

volvo1975

Should be there

carnut222

try unplugging the mass airflow meter and see if it starts...

volvo1975

I reckon its this relay or the coolant sensor

volvo1975

The ecu coolant sensor

There is no relay on the bottle or any relay dangling about in that area. And I'm sure the car would still start with a bad sensor. Wouldn't it only be hard to hot start if it was bad?

volvo1975

As i said we had same trouble the car would not start.. if sensor was bad.. took like 20 tries to go once warm was fine... that sensor is so important

Try some start you bastard (ether). If the engine kicks over you have a fuel problem.
And at least you are not chasing your tail and a spark problem causing the issue.
Are your injectors firing? Do you have voltage to them?

I'm not sure if the injectors are firing. I don't own a volt meter as well

volvo1975

The relay i mentioned controls the injectors

Used start ya bastard like I have before and it went for a bit just running on the spray but my number 1 fuse littelry melted idk why. New fuse board now really pissed me off.

volvo1975

Im telling you ..its either of those 2 items. .we had identical problem
