Friend Andy here in ABQ has a 2.1L that won’t start,, Cranks well but NoStart ~ 

Spent a bunch of hours yesterday diag'ing but No Joy,,,  

        Info from Andy

with starter fluid it ignited, like poofed, but did not run 

Verified- 
spark - all cylinders whole path between coil and sparkplugs (1and2 were not sparking so those were replaced. 
fuel - took off bolt on Tee, squirted fuel almost to ceiling 
injectors - removed all injectors and fuel squirted 
tried known good ecu (and this ecu in running van worked) 
tried another (unverified) AFM 
Distributor gear was off a bunch, reset per bentley. verified via timing light Cyl 1 was getting spark at TDC. 
Temp 2 - tried unplugged and shorted 
tried starting with fuel relay removed 
quick checked cyl pressure on 2 while plug was out, good compression pushed my finger out. due to compression the engine was hard to turn with the plugs in. 

Additional data- 

When we opened pass’ side valve cover to verify TDC valve position, a bunch of fuely oil spilled out. even after all that drained the dipstick showed overfilled to upper twist 

In general the thing smells fuely - could be from all the cranking. 

It hasn't run since I had it. PO said it ran and then he did something and then it didn't run. 

        In addition to info from Andy above I'll add >

Battery shows 12.58VDC while cranking

Tried New Ignition Switch

Swapped in known good Coil

Swapped in known good IAC Relay 

Tried cranking with WOT just incase flooded
