I need help

[BrokenSHO&heart]

Hey guys, I have a 95ATX that has been in the family since new. It had an engine replacement in 2007 and shortly after the AC compressor went out. It was parked until last year I had it towed to my house to revive her and I've replaced a ton of parts and drained all the fluids and refilled them and I still can't get it running. Is there anyone local who wants to come take a look an help out?(DFW TX) I'm in love with this thing and need it back on the road.

parts replaced:
ECU
J box
Crank position sensor
Fuel pressure regulator
Fuel pump
Plugs
Thermostat
Fuel filter
AC compressor
Thermo housing
Battery
And more I'm sure.
Took it to a shop by my house (useless) they said they didn't have the diagnostic tools to figure it out but it's a spark issue, which I call BS because I started it last year on starter fluid unless the new ECU is not telling it to fire during ignition. I'm lost.

most likely injectors are all gummed up from old gas sitting in them for years. remove them and clean properly and try again.

Does it have compression?

I have had the same issue with my 3.2. I replaced all the same parts which you have already replaced and it turned out to be the TPS and it could very well be the issue for your car as well.

Will give it a try thanx

Not sure how to test for compression

Will definitely replace that next

Not sure how to test for compression

Get a compression gauge and check the compression. If you have no compression it will not allow you to start. I faced the same issue when I resurrected a SHO that sat for 5yrs.

Not sure how to test for compression

As Loudsho said, get a compression tester (you can buy or rent one from most auto parts stores). They are fairly easy to use. All you do is take out a spark plug, replace with the compression tester, unplug the DIS and then crank the engine a few times (the manual for the tester will explain the details of what to do). What will happen is that the gauge will read how much compression there is in that particular cylinder, and you move from one cylinder to another to see if there are any anomalous results.

In this engine if you are low on compression it would probably be a head gasket or warped head. I saw a Geo Metro once that had no compression in two adjacent cylinders due to a cracked block. I'm not sure if anyone here has managed to crack a 3.0 or 3.2 block yet.

When I had the low compression I added a little oil to each piston and it helped it build up enough compression to start.

correction - in this engine, if you are low on compression it is most likely a piston with stuck rings. head gasket failures are rare but possible. I have yet to see a warped head on one of these.

adding the oil to the cylinder as Loudsho92 suggests above will often solve the stuck ring problem to allow startup. the solution to the stuck ring problem is to pull the heads, pull the pistons and r/r the rings. often, it can be workable if you use a really good high-detergent oil for a while, like the Motorcraft semi-synthetic.

did you check for spark?

is your DIS (ignition module) grounded? 4 5.5mm bolts, make sure the module is not horribly corroded. if it is clean the back of it and re install. Do you have the 2 bolts in your crossover tube (the piece on the pass side of the intake). The crossover tube is the ground for your DIS and if it is not bolted down it can cause the car not to start and is often overlooked after servicing the giant intake
