Hello Ken,

I have the vehicle listed above VQ40.
Intermittent start issue, spins over but wont start. There's spark and fuel, and I also checked all fuse and relays still not finding anything. No engine management light showing on the dash for this particular vehicle.
It has 300,000 and something on the clock.

What could this be?

Please help.

We need to step back and find out when did this start and were there any recent repairs?

If not and this just started one morning after the vehicle was running fine then we need to confirm how you checked for fuel and spark.

Here is a guide that will help with basic info on this issue as we may need to confirm a lot of this:

Even if you have fuel we need to confirm you have the proper fuel pressure in order to find out if this is the issue.

So that means we need to follow this guide and make sure because if you have fuel, spark, and compression the engine should start. So we are either missing one of them or we have a sensor issue which would normally set a code. So if you have no codes then we are missing one of the others.

I attached the process from the manual below for your review.

Let us know what you find with this and we can go from there. Thanks
