A friend bought this car and it wouldnt run when he bought it. We have fuel to the injectors and it will "kinda" run as long as you hold down the key but stop as soon as you let off the key. He was told it just would not start one morning and they wanted it out of the yard.

Verified glow plug operation and did a compression check, this is what I got.

So I am thinking blown head gasket or some bad valves. was gonna pressurize a cylinder with the valves closed and see where the air went, but pretty much the head will have to come off any way right.

Any suggestions on other things to check? Thanks in advance.
